The gyros that Crossbow The gyros that Crossbow manufactures use a technology manufactures use a technology called MEMScalled MEMS
MEMS is Micro-Electro-Mechanical MEMS is Micro-Electro-Mechanical SensorsSensors
These sensors are on the silicon These sensors are on the silicon and provide much better and provide much better calculationscalculations

The AHRS500 would be the best The AHRS500 would be the best choice because of the functions it choice because of the functions it provides and its serial interface, provides and its serial interface, but it might cost way too muchbut it might cost way too much
The tilt sensors would be cost The tilt sensors would be cost effective but there was no effective but there was no indication if they would work at indication if they would work at altitudealtitude
