ANT-GPS-Series GPS Antenna
The ANT-GPS-Series are space qualified L-band patch antennas tuned to the GPS frequency bands.
Our low-profile ANT-GPS Series active GPS antenna’s developed by AAC SpaceQuest provides hemispherical coverage and a built in Low Noise Amplified (LNA). This antenna is ideal for MicroSats and SmallSats but can also be mounted recessed on CubeSats.
Our GPS antenna have over 15 years of successful on-orbit flight operations heritage on our AAC SpaceQuest spacecraft as well as being deployed for a global clientele.
The ANT GPS units are all low-profile by design. These modular GPS antennae have versatile cable connection points to allow for ease of integration within the bus.
The frequency band and constellation on these units can be configured to match the GNSS receiver selected. From single frequency to multi-frequency, multi-constellation.
With over 15 years of on-orbit heritage these units have been developed to adapt to the ever-evolving constellations and associated frequencies.
