Harris Corporation has been awarded a two-year, $16 million contract by Boeing to support the development and integration of the Launch Anomaly Disposal Operations (LADO) segment of the US Air Force Global Positioning System (GPS) IIF satellite program.
According to the Harris Corporation, LADO is a COTS, PC-based telemetry command and control system and simulator. It is designed to track Air Force GPS satellites after launch, position them in low orbit, check out and verify their operating parameters, and then propel them into high orbit.
Once control of the satellites is transferred from LADO to Mission Control, LADO continues to monitor the health and status of the satellites. If an anomaly is detected that cannot be resolved by mission control, LADO uses a high-fidelity simulator to locate and repair the problem. If repair is not feasible, LADO disposes of the satellite.
Boeing Integrated Defense Systems recently received approval from the US Air Force to begin production of the first three satellites for the GPS IIF program, which will provide new capabilities, including new signals for civilian users and critical, secure operational military codes for the US armed forces.
GPS IIF also is compatible with the US Air Force’s Expendable Launch Vehicle (EELV) and will provide 20 percent more on-orbit life than previous GPS spacecraft.
