About Ground Control Systems
Ground Control Systems, doing business as GSC Satellite, is a San Luis Obispo, California-based manufacturer and reseller of satellite communications equipment and services that operates exclusively as a prime contractor to federal agencies across 49 distinct customer organizations. The firm holds a small business designation and competes in both full-and-open and total small business set-aside procurements, with recent awards split between non-set-aside and total small business vehicles.
GSC Satellite's capability portfolio centers on satellite telemetry, airtime provisioning, and network management for federal environmental and operational monitoring systems. Representative work includes a $478,880 Iridium satellite services contract with the U.S. Department of Agriculture's Natural Resources Conservation Service (awarded September 2025) to support the Snow Survey and Water Supply Forecasting Program, providing Iridium airtime and equipment support for 204 actively transmitting radios and 38 standby units at remote weather stations across the western United States through September 2030; a $55,440 purchase order from the Environmental Protection Agency's Office of Air and Radiation (awarded February 2026) to provide network services for 140 BGAN hardware devices supporting the RadNet Fixed Monitor systems distributed across the United States; and a $17,107 purchase order from the National Oceanic and Atmospheric Administration (awarded April 2023) for Rockfleet satellite tracker software and monitoring for NOAA vessels.
Customer concentration remains dispersed. The top five funding organizations account for 31 percent of awards by count but only 35 percent by combined potential value, indicating a long-tail portfolio: the Environmental Protection Agency leads on dollars ($421 thousand across three awards), while the United States Marine Corps leads on volume (19 awards, $163 thousand combined potential value). GSC Satellite places task orders on the Federal Supply Schedule GS35F0417P (32 task orders, $260 thousand combined potential value). The vendor's award activity has remained modest—one to two awards per year since 2021, with a combined portfolio of $3 million in potential value across 147 prime awards and $2.4 million obligated. Primary NAICS categories reflect the satellite and telecommunications focus: Satellite Telecommunications (49 awards), Software Publishers (33 awards), and All Other Telecommunications (30 awards).
