SATELLITE SIMULATORS WITH DEBOOST SYSTEM AND SPACE VOLUMETRIC ENVELOPES

by Mark Kanne, George Irwin, and Daniel Letson

ABSTRACT

This paper describes a low-cost solution to several problems associated with satellite testing and manufacturing, by using a low cost satellite Simulator which maintains the characteristics of the real Satellite in structure, natural frequency, mass, launch vehicle interfaces, orbital characteristics and de-orbit capability.

Problems of manufacturing and schedule are solved with the simulators, which can be produced in weeks, compared to months for the actual satellite with real electronics, solar arrays, antennas, and Bus structure. This satellite simulator can be used in ground testing the di spenser or checking the Lannch Vehicle interface for loads, interface compatibility, dispensing and fairing jettison.

This satellite simulator can also be flown on a demonstration launch, supplying credible flight test data without contributing to 'space junk,' through its ability to be commanded to de-orbit after the orbital data and launch data have been obtained.

PROBLEMS ENCOUNTERED

This invention solves the problems of Satellite high fidelity structural testing, launch and deboost from earth Orbit by using a low-cost Satellite High Fidelity Simulator. This simulator is substantially cheaper in cost but maintains the characteristics of the real Satellite, with the actual bus structure, natural frequency, mass, launch interfaces with the Launch vehicle, orbital characteristics and de-orbit capability.

Problems of manufacturing and schedule are solved with the new satellites which can be produced in weeks compared to months for the actual satellite with real electronics, solar arrays, antennas, real Bus structure. This new satellite is also used in

ground testing the dispenser or Launch Vehicle interface for loads, interface compatibility, dispensing, fairing jettison. This satellite solves the problem of "space junk." Previous satellites did not de-orbit for many years; now this system can be commanded to de-orbit after the orbital data and launch data are complete and analyzed. This vehicle utilizes the real bus structure providing data during launch and orbit of its behavior in actual flight test compared to analytical results.

The invention solves numerous problems associated with the prodnction of Satellites. High rate satellite production requires process development to reduce cycle time and risk. On many programs, "pathfinding" is the method used to develop these processes for the launch processing and final satellite integration phases. The satellite volumetric envelopes (SVE) allow us to do pathfinder activities early, prior to the availability of qualified flight hardware. The time-savings allows us to optimize our processes and validate the function I fit on dispensers and launch vehicles.
