Navigation is a field that has been fascinating humankind for thousands of years and these pillars have been evolving with new technological advancements. There has been a constant push to find a navigation system that is accurate, continuous and easy to afford. Furthermore, Cost and space constraints are currently driving manufacturers of Guidance, Navigation & Control systems to investigate and develop next generation of low cost and small size navigation systems to meet the fast growing mapping and location services market demands. Advances in inertial navigation and more specifically Micro-Electro-Mechanical Systems (MEMS) technology have shown promising light towards the development of such systems. MEMS are integrated micro devices or systems combining electrical and mechanical components whose size ranges from micrometers to millimeters. MEMS is an enabling technology and the MEMS industry has a projected 10-20% annual growth rate to reach 240 billion US$ market by 2015. Advances in MEMS technology combined with the miniaturization of electronics, have made it possible to produce chip-based inertial sensor for use in measuring angular velocity and acceleration. These chips are small, lightweight, consumes very little power, and extremely reliable. It has therefore found a wide spectrum of applications in the automotive and other industrial applications. MEMS technology, therefore, can be used to develop next generation Guidance, Navigation & Control systems that are inexpensive, small, and consume low power (microwatt). However, due to the lightweight and fabrication process, MEMS sensors have large bias instability and noise, which consequently affect the obtained accuracy from MEMS-based IMUs. For land MMS, introducing auxiliary velocity update in the body frame, (e.g. non-holonomic constraint and odometer signal) is an option to solve the problem. This presentation will introduce some of the development of integrated navigation systems by the Mobile Multi-Sensor Systems (MMSS) Research Group at the University of Calgary. Some of the developed system’s accuracy performance will be demonstrated through land/airborne vehicles and personal units’ tests

The Center for Orbit Determination in Europe (CODE) is contributing as a global analysis center to the International GNSS Service (IGS). Since 2012 CODE also contributes to the multi-GNSS pilot project (MGEX) of the IGS. The list of satellite systems included in the CODE MGEX (COM) orbit and clock solution has been extended step-by-step in recent years. Today, it includes five satellite systems, namely GPS, GLONASS, Galileo, BeiDou, and QZSS. CODE's MGEX solution is updated from time to time. The generalization of the CODE solar radiation pressure (SRP) model in 2015 significantly improved the orbits and clock corrections of satellites with

elongated bodies (in particular Galileo and QZSS) when the satellite's attitude is maintained by yaw-steering. Currently we focus on improving the orbits of QZSS and BeiDou satellites, when they are moving in the orbit normal mode. The COM orbits are validated by computing SLR residuals. The COM clocks are validated using linear fits through the time series of epoch-wise clock corrections. We present the current status of the COM products and latest results from our current orbit modelling experiments.

Characteristics of Atmospheric Waves in the Middle Atmosphere

Revealed Using GNSS RO Temperature Profiles

1 Toshitaka Tsuda 1 Research Institute for Sustainable Humanosphere (RISH), Kyoto University

Tel: +81 774 38 3804 Email: [email protected]

GNSS radio occultation (RO) measurements from a low-Earth orbit (LEO) satellite produce accurate temperature and humidity profiles below about 50 km and 10 km altitudes, respectively. By applying a holographic analysis, such as Full Spectral Inversion (FSI) algorithm, height resolution of temperature profiles in the stratosphere can be as good as 100-200 m. GNSS RO data is very useful not only for improvement of both global and meso-scale numerical weather prediction (NWP) models through data assimilation, but also for the studies of medium-scale temperature disturbances caused by atmospheric waves in the middle atmosphere. We discuss in this paper the behavior of the atmosphere dynamics in the middle atmosphere (10-100 km altitude), focusing on excitation, propagation and dissipation processes of atmospheric gravity waves and their important role in driving the general circulation. GNSS RO data are available globally, including the ocean as well as the southern hemisphere where operational ground-based observations are sparse. In particular, large amount of temperature data collected by the COSMIC GNSS RO mission have provided a unique opportunity for us to understand the global behavior of the middle atmosphere dynamics and ionosphere physics. We studied a global morphology of atmospheric gravity wave activity. We found a correlation between the wave energy (temperature variance) and tropical convection, wave-mean flow interaction and wave filtering by the background QBO winds. In the northern hemisphere winter months, most of the gravity wave energy is related to the sub-tropical jet and additional enhancement by topography. In the polar region, gravity wave generation due to geostrophic adjustment of the polar vortex and orographic effects are investigated.

The central task of SINS/GNSS integration system is to effectively blend the SINS and GNSS data to generate an optimal navigation solution. Generally, the Kalman filter is the most common technique for the estimation of SINS/GNSS integration system, but the estimation accuracy of the Kalman filter relies on

the correct a priori information of the system models and noise statistics. However, the correct statistical knowledge of measurement noise is hard to obtain in practice and the stochastic characters of GNSS noise may change with the maneuver of vehicles, the electromagnetic interferences and other factors, which will bring in the noise uncertainties for the filter. In fact, the noise statistics greatly affect the weights between the estimated state of the optimal filter and the new measurements from GNSS. In other words, the uncertainties in the covariance parameters of GNSS measurement noise will degrade the performance of Kalman filter significantly, and even cause the filter to be divergence. To solve the estimation problems caused by the GNSS measurement uncertainty, an innovation covariance-based adaptive Kalman filter is proposed in this paper. The basic idea of the adaptive Kalman filter is to keep the innovation sequence in the filter to be white Gaussian noise, which is a necessary condition for an optimal filter. First of all, a regulatory factor is introduced to modify the filter gain with the estimated innovation covariance timely. On the other hand, adapted to the practical maneuvers and system dynamics, several individual innovation covariance estimators with different window size are weighted to generate an accurate innovation covariance, which is considered as the source of the adaptive estimation. Moreover, the results of the SINS/GNSS integration system shows that the proposed adaptive Kalman filter has better estimation accuracy and robustness in the presence of GNSS measurement noise uncertainties.

Global Surface Mass Variations from Inversion of GNSS+ECCO and

from GRACE

Xiaoping Wu and Michael B. Heflin Jet Propulsion Laboratory, California Institute of Technology, Pasadena, USA

Global surface mass variations induce several distinct geodetic signatures of gravity changes, surface deformation, geocenter motion, and Earth rotation variations. Their measurements by different geodetic technologies are complementary and also contain overlapping information to provide valuable redundancies for cross-calibration and validation. Since Global Navigation Satellite System (GNSS) data are restricted to land areas and some islands with considerable geographic inhomogeneity, global inversions of load-induced deformation can benefit significantly from inclusion of global ocean bottom pressure models and some loose a priori information. The global pattern of such inverted surface mass variations has been shown to generally agree with that from the GRACE data. But significant differences in amplitudes over large regions persist over the last decade of investigations. Now, with burgeoning number of global GNSS stations, and advanced hardware and software, GNSS data quality has improved substantially. We will show here that the newly inverted global surface mass variation using reprocessed (RePro 2.0) GNSS data and JPL’s ECCO ocean model with self-gravitation and loading looks strikingly similar to that derived from the GRACE data. The improved GNSS data also allow us to push the boundaries of inverse resolution and accuracy, and provide an opportunity to bridge possible spatiotemporal coverage gaps of GRACE and GRACE follow-on missions.

The Black Sea is located in converged regions with the Eurasia, Africa and Saudi Arabia plates, while the vertical motion along the Black Sea coast is not clear due to fewer observations. The Tide Gauge (TG) record shows the relative sea variation to the land, while the satellite altimetry provides the absolute sea variations in the Earth’s center fixed frame. Accordingly, the difference of both observations is the vertical land motions at TG stations. In this study, the vertical land motion along the Black Sea coast is investigated at 12 tide gauge sites (Poti, Batumi, Tuapse, Varna, Bourgas, Constantza, Amasra, Igneada, Trabzon-II, Sinop, Sile and Istanbul) from the TG records and the satellite altimetry (SA) data. The results show land subsidence at Poti, Tuapse, Varna, Bourgas, Igneada and Trabzon-II, and uplifts at Batumi, Constantza, Sinop and Istanbul. On the other hand, Amasra and Sile present no significant vertical motion. Furthermore, the vertical motion rates are compared with those from nearby continuous Global Positioning System (GPS) observations, which show good agreement with GPS-derived vertical velocities and confirm vertical motions from SA-TG. Finally, some possible reasons on vertical motions are discussed with related present geodynamics along the Black Sea coast.

Email: [email protected] The Global Geodetic Observing System of the IAG has issued a Call for Participation to research scientists, geodetic research groups and national agencies in support of the implementation of the IUGG recommendation for a Global Navigation Satellite System (GNSS) Augmentation to Tsunami Early Warning Systems. The call seeks to establish a working group to be a catalyst and motivating force for the definition of requirements, identification of resources, and for the encouragement of international cooperation in the establishment, advancement, and utilization of GNSS for Tsunami Early Warning. During the past fifteen years the populations of the Indo-Pacific region experienced a series of mega-thrust earthquakes followed by devastating tsunamis that claimed nearly 300,000 lives. The future resiliency of the region will depend upon improvements to infrastructure and emergency response that will require very significant investments from the Indo-Pacific economies. The estimation of earthquake moment magnitude, source mechanism and the distribution of crustal deformation are critical to rapid tsunami warning. Geodetic research groups have demonstrated the use of GNSS data to estimate earthquake moment magnitude, source mechanism and the distribution of crustal deformation sufficient for the accurate and timely prediction of tsunamis generated by mega-thrust earthquakes. GNSS data have also been used to measure the formation and propagation of tsunamis via ionospheric disturbances acoustically coupled to the propagating surface waves; thereby providing a new technique to track tsunami propagation across ocean basins, opening the way for improving tsunami propagation models, and providing accurate warning to communities in the far field. These two new advancements can deliver timely and accurate tsunami warnings to coastal communities in the near and far field of mega-thrust earthquakes. This presentation will discuss the justification for and the details of the GGOS Call for

High-order ionopsheric effects on GPS-estimated tropospheric delay

gradients

2 Shanghai Astronomical Observatory, Chinese Academy of Sciences, Shanghai 200030, China The zenith tropospheric delay (ZTD) and tropospheric delay gradients (TDG) can be estimated from dual-frequency GPS observations with removing ionospheric delay, which are used for atmospheric study and weather forecasting. However, high-order ionospheric delays are normally ignored in ZTD and TDG estimation. In this paper, high-order ionopsheric effects on GPS-estimated tropospheric delay gradients are investigated from 30 days of GPS data in June 2011 at 8 GPS stations in Turkey. Firstly, the second and third-order effects on GPS data are corrected in RINEX using IGRF11 model, and then the tropospheric delay gradients (TDG) are obtained from raw and corrected RINEX data with GAMIT software. Results show that high-order ionospheric effects are up to 4 millimeters on North-South(NS) gradient and 6 millimeters on East-West(EW) gradient during this period. Solar activity is an important effect on ionospheric activities. When data during the low and peak solar activity days are used for same stations in 2011, and high-order ionopsheric effects are up to 3 mm in NS and EW gradient in low solar activity days and 8 mm in NS and EW gradient in peak solar activity days.

Email: [email protected] GNSS is a well established atmospheric observing system which can accurately sense water vapour, the most abundant greenhouse gas, accounting for 60-70% of atmospheric warming. Water vapour observations are currently under-sampled in operational meteorology and obtaining and exploiting additional high-quality humidity observations is essential to improve severe weather forecasting and climate monitoring. Inconsistencies introduced into long-term time series from improved GNSS processing algorithms make climate trend analysis challenging. Ongoing re-processing efforts using state-of-the-art models are underway which will provide consistent time series’ of tropospheric data, using 15+ years of GNSS observations and from over 600 stations worldwide. These datasets will enable validation of systematic biases from a range of instrumentation, improve the knowledge of climatic trends of

Ionospheric scintillation refers to the amplitude attenuation and phase jitter effects of onospheric irregularities on the travelling through satellite navigation signals. Ionospheric scintillation will influence satellite navigation signals process and further impact satellite navigation erformances. Ionospheric scintillation is under focus by the related research fields. Currently the use of GNSS measurements to observe ionospheric scintillation has been widely accepted as common method, and has achieved lots of research achievements. Cornell University GPS Lab and Colorado University have designed hardware GNSS ionospheric scintillation monitors. The Cornell GNSS ionospheric scintillation monitor has been widely used in different regions all over the world, and it has been installed in Sanya, Hainan to monitor low latitude scintillation by Chinese researchers. The researchers in Colorado University make performance comparisons for different hardware ionospheric scintillation monitors, and further deeply analyze scintillation time-frequency features for data collected in Alaska at high latitudes and the Gulf of Mexicoat low latitudes. Ionospheric scintillation behaviors of different satellite navigation systems have been also considered by the researchers. The previous studies shed lights on theoretical and experimental studies on ionospheric scintillations. Based on the above work, this paper focuses on strong multipath impacts on GNSS ionospheric scintillation observation. Provided by Space Weather Services data of Australia Government Bureau of Meteorology, a five-year real GNSS ionospheric data has been thoroughly analyzed from time-frequency statistical aspect. The results show that due to impact of sea multipath, amplitude scintillation index and phase scintillation index calculated for Willis island monitor station behave in quite unique characteristics, compared with other monitor stations in Australia. We further investigate this phenomenonwith Fresnel reflectiontheory, establish sea multipath model of Willis islands, and derive quantitativedescription of sea multipath error behavior andpropagation mechanism in GNSS processing. It turns out that relationship between sea multipath error and elevation demonstrate strong nonlinearity

coupling, what’s more, sea multipath error doesn’t decrease with increase of elevation. This greatly has influence on accuracy measurements of GNSS ionospheric scintillations. To address this problem, this paper proposes a pre-process filtering method to weaken the impacts of strong sea multipath on GNSS ionospheric scintillation observation. The proposed methodis verified by numerical simulation. The rest of this paper is organized as follows: section II introduces basic theory of GNSS ionospheric scintillation, such as calculation of amplitude scintillation factor and phase scintillation factor. Section III proposes data process and analyzation of Willis islands in Australia. Section IV introduces Fresnel reflectiontheory and procedure of
