JAVAD GrAnt Antenna Designed for High Performance
The GrAnt by JAVAD GNSS is a versatile high-performance antenna.
With J-shield — the JAVAD GNSS filter that protects GPS L1, Galileo L1 and GLONASS L1 bands — the GrAnt antenna can track GPS, GLONASS, Galileo, BeiDou, WAAS, EGNOS, MSAS, GAGAN and QZSS signals. J-shield brings in all the useful signals intact and rejects out-of-band signals with the slope of about 12 dB/MHz. Similarly, the filter protects GPS L2, GPS L5, GLONASS L2, GLONASS L3 and Galileo L5, and has slope of about 9 dB/MHz. The filters have been extensively tested with five different innovative tests that prove that the filters also improve the performance of GNSS receivers.
The GrAnt antenna can be mounted on flat surfaces with four screws or mounted on standard poles (5/8-11 or 1-14 inch thread). The antenna cable can be connected via the standard TNC (N-type optional) connector on its side or routed through the center of the antenna for ultimate protection in harsh environments.
An optional ground plane can be purchased to increase multipath mitigation.
The top-level model, the GrAnt-G5T, supports a wider band to accommodate additional signals, with frequencies of 1555-1610 MHz and 1164-1300 MHz. Full signal capability of the GrAnt-G5T is:
- GPS L1/L2/L5
- GLONASS L1/L2/L3
- Galileo E1/E5ab/E6
- BeiDou B1/B2/B3
- WAAS L1/L5,EGNOS,MSAS,GAGAN
- QZSS L1/L2/L5/LEX
