LOCKHEED MARTIN AND ROVSING TO COLLABORATE ON SOLAR ARRAY SIMS
Lockheed Martin and Rovsing Collaborate to Bring Solar Array Simulators to Market:
• Brings together Rovsing’s Solar Array Simulator suite capability for testing power output and Lockheed Martin’s test and integration operations.
• Identifies new test equipment capabilities in driving satellite test efficiencies.
It’s hard to simulate a star, but a new effort between Rovsing A/S and Lockheed Martin will do just that. They are collaborating to bring better solar simulators to bear in a market of increasing demand for a range of spacecraft sizes. Solar simulation equipment tests power and electrical systems for all spacecraft, so simulating the sun’s power on orbit is critical for satellites under development here on Earth. Rovsing offerings a versatile, highly modular and efficient testing system for high-power solar arrays, which are used for Earth observation, science or telecom satellites as well as for deep space missions. The Solar Array Simulator (SAS) users already include Orion, ExoMars and MetOp-SG, and more missions are possible with Lockheed Martin behind it.
The project was approved by the Danish Business Authority under the Guidelines for Industrial Co-Operation in Denmark. Lockheed Martin and Rovsing have completed the initial test and demonstration project for the Rovsing Power Special Check-Out Equipment (SCOE) Reference System incorporating Rovsing’s RO-5100 Solar Array Simulator test product. The project centered around testing the Solar Array Simulator (SAS) Modules. Rovsing supplied a fully integrated rack with SAS Modules, second level protection units (SLP), and Controller Software (SW) Suite. DC tests were performed to verify performance and programmability of the SAS Modules. The Rovsing curve definition SW was used to create several IV curves for the tests. IV curve bias points were verified running under different load conditions comparing the measured values to the ideal values obtained from the Rovsing curve definition SW.
Headquartered in Bethesda, Maryland, Lockheed Martin is a global security and aerospace company. Headquartered in Skovlunde, Denmark, Rovsing is a leading European company providing since 1992 power and electrical ground support equipment for European and US space missions as well as software and independent validation & verification services.
