GLONASS: The Next Generation?
| Abstract: | The Russians made little fanfare about the thirtieth GLONASS launch, which placed three new satellites into orbit on December 1, 2001. However, initial reports stated that one of the satellites was the long-awaited GLONASS-M, which would improve satellite lifetimes, integrity checking, and interoperability with GPS. Words about GLONASS-M were later retracted, but one of the satellites is notably different and has not been declared operational. It has GLONASS-M-type status bits, but the Russians would only say it is undergoing flight tests. The satellite appeared to be having serious problems, and its survival was in question, but those problems have subsided for the time being. The other two satellites launched at the same time are performing well, and the ground segment continues to maintain the system. However, the useable satellite count is only seven, up one from last September. Several satellites reported as dead at last year's meeting were formally withdrawn, and another quit in January. GLONASS spokespersons continue to present an optimistic future, stating that new fiscal policies will provide continued funding for the program, and predicting another launch later this year. |
