WebThe ITT Industries-developed GPS IIR satellite payloads have been on-orbit since 1997 providing outstanding signal-in-space performance. Much of credit for this outstanding performance can be given to the GPS IIR Time Keeping System (TKS) and the GPS-IIR spacecraft bus, which keeps the payload in a mechanically and thermally stable condition. WebThe redistribution of the transmit power among different GPS signal components is called flex power, and it is implemented on modernized GPS satellites starting with Block IIR-M. The purpose of the flex power is to increase signal protection against jamming. It has been mostly active since the beginning of 2024 in different flex power modes and is visible in …
