Making SBIRS Simpler: Air Force Undersecretary Ronald Sega told lawmakers that sensor technology has moved “a great deal in the last 10 years” since the start of the Space Based Infrared System satellite program. So much so that he believes “a simpler design is possible.” And, that likely will lead to a new program termed Alternate Infrared Satellite System (AIRSS), which some analysts have said will replace SBIRS GEO sat No. 3. Sega said that the Air Force will evaluate the “performance and progress and development” of GEO-1 to gauge whether to proceed with GEO-3. He acknowledged a “parallel” effort would investigate the AIRSS approach.
The Space Force is playing midwife to a new ecosystem of commercial satellite constellations providing alternatives to the service’s own Global Positioning Service from much closer to the Earth, making their signals more accurate and harder to jam.
