A geostationary orbit occurs when an object (satellite) is placed approximately 37,000 km (23,000 mi) above the Earth’s equator with the characteristic that, from a fixed observation point on the Earth’s surface, it appears motionless. A satellite is in an inclined orbit when its orbital plane is tipped some number of degrees from the horizontal …

Evolutionary Acquisition for Space Efficiency (EASE) is a procurement approach that seeks stable production and strategic sub tier management through the block buy of two space vehicles employing fixed-priced contracting. In addition to block-buy procurement, EASE includes RDT&E funding for a Capability and Affordability Improvement Program (CAIP). CAIP seeks to improve manufacturability and lower recurring …

A Link Budget shows all of the gains and losses from a transmitter, through the medium (free space, cable, waveguide, fiber, etc.) to the receiver in a telecommunication system. It’s used to predict the performance of a transmitter and receiver communication link to show in advance if its performance is acceptable, or if one option …
The following is a list of some of the more heavily used frequency bands for space communication. Specific frequencies may be found in the links provided at the end of this note. VHF Band 136 – 138 MHz: This band was used heavily by many different types of satellites in the past. Today (2012), most …

Three major differences that make “Space Systems” unique and set them apart from a non-space system are: The Space Environment Unattended Operation And The Implications of The Ultimate High Ground Space Environment The Space environment is extremely harsh. It places additional constraints on the design and operation of satellites, components, and parts of the …
The Space Systems Acquisition Policy (SSAP) (DTM 09-025) model emphasizes the decision needs for “high-tech” small quantity National Security Space (NSS) programs. DoD Space Systems are those space programs listed in the space virtual Major Force Program (MFP) maintained by the Office of the Secretary of Defense (OSD) Director, Cost Assessment and Program Evaluation …
A Polar Orbit (PO) is an orbit in which a satellite passes above or nearly above Earth’s North and South poles on each revolution. It, therefore, has an inclination of (or very close to) 90 degrees to the equator. Except in the special case of a polar geosynchronous orbit, a satellite in a polar orbit …
The Satellite Industry Association (SIA) is a Washington D.C. based trade association representing the leading global satellite operators, service providers, manufacturers, launch services providers, and ground equipment suppliers. Website: Satellite Industry Association (SIA) Since 1995, SIA has been the unified voice of the satellite industry on policy, regulatory, and legislative issues affecting the commercial …
