OTTAWA COMBINED LEO-GEO PROCESSING

COMMISSIONING REPORT

ACTION REQUIRED

The Joint Committee is invited to:

a) review the commissioning report for combined LEO-GEO processing using the

Ottawa LEOLUT, Cospas-Sarsat identifier 3168 and GEOLUT 3167 provided atAttachment 1;

b) note that the LEOLUT 3168 used for the combined LEO-GEO processing is a

LEOLUT whose commissioning report has been submitted for JC-19 and approved by

CSC-35; and

c) note that the GEOLUT 3167 whose commissioning report has been submitted for

JC-21 and approved by CSC-39, tracks the GOES-12 (ID 212) satellite.

1. SUMMARY INFORMATION

1.1 406 MHz SARP Test Summary

The 406 MHz SARP test is reported in a separate LEOLUT Commissioning Report.

1.2 406 MHz SARR Test Summary

The 406 MHz SARR (Ground SARP) test is reported in a separate LEOLUT Commissioning

Report.

1.3 406 MHz SARP/SARR Combined Test Summary

The 406 MHz SARP/SARR Combined test is reported in a separate LEOLUT

Commissioning Report.

1.4 Combined LEO-GEO Processing

The LEOLUT 600 system is capable of combined LEO-GEO processing. The testing of this

capability is reported in the three paragraphs that follow.

1.5 Combined SARP/GEOSAR Test Summary

The 406 MHz SARP/GEOSAR test was performed for 14 days and in that time 416 passes,

for satellites S7, S8, S9, S10, and S11 were scheduled and tracked. The system located 145

nominal solutions, with a Location Accuracy (within 5 km) of 100%, an Ambiguity

Resolution of 100%, and an Error Ellipse Performance of 37.2%.

1.6 Combined SARR/GEOSAR Test Summary

The 406 MHz SARR/GEOSAR test was performed for 14 days and in that time 416 passes

for satellites S7, S8, S9, S10, and S11 were scheduled and tracked. The system located 543

nominal solutions, with a Location Accuracy (within 5 km) of 99.3%, an Ambiguity

Resolution of 100%, and an Error Ellipse Performance of 37.9%.

1.7 Combined SARP/SARR/GEOSAR Test Summary

The 406 MHz SARP/SARR/GEOSAR Combined test was performed for 14 days and in that

time 416 passes for satellites S7, S8, S9, S10, and S11 were scheduled and tracked. The

system created 519 nominal solutions during this test, with a Location Accuracy (within 5

km) of 100%, an Ambiguity Resolution of 99.0%, and an Error Ellipse Performance of38.7%.

1.8 Anomalies

1.8.1 Alarms

The logs were examined for the period spanning the Combined LEO-GEO Commissioning

Test looking for anomalies. There were no reported circumstances deemed of significance in

the evaluation of the Commissioning results.

1.8.2 Large Location Errors

During the collection of the data for these Commissioning statistics, there were some

solutions that had errors large enough to require special attention. These solutions are listed

in the following paragraphs, with an indication of the probable cause of the relatively large

error in each case.

There were two SARR/GEOSAR marginal solutions with a location error greater than fifty

kilometers. Solutions A and B have a small CTA.
