The MRPA-3A MRPA active GNSS antenna from GPS Source is a professional grade, active horizon-nulling GNSS antenna designed for long term reliability. Based on the acclaimed GNSS antenna base model, the MRPA (Modified Reception Pattern Antenna) is designed to null terrestrial interferences arriving at low elevation angles.
Designed to support the Warfighter, the portable, yet precise GNSS antenna is built for tough applications. The radome is made of a high-grade polymer, with a design to protect from UV, rain, lightning, chemical, and jet fuels. The MRPA-3A active horizon-nulling GNSS antenna is available with multiple connector options and multiple colors (per FED-STD-595B).
The MRPA series was designed for both military and civilian applications, and is available in two models, the MRPA-3SA side mount and the MRPA-3A bottom mount.
The MRPA-3A GNSS antenna comes with many available options to meet specific needs. Available product options are listed in the datasheet.
