TOAS100D Dual Antenna Satellite Direction Finding System-Fornitore globale

7th Floor, East Area, Building 4, Shangdi Science and Technology Building, No. 8 Shangdi West Road, Haidian District, Beijing

The TOAS100D dual antenna direction finding system is a miniaturized dual antenna direction finding system based on the latest multi RF unit synchronization technology from Eastern Union. The system adopts more precise carrier phase relative positioning differential technology, thereby achieving high-precision and high stability heading measurement in both static and dynamic situations. The GPS measurement unit of the TOAS100D dual antenna direction finding system simultaneously receives dual GPS satellite signals through dual antennas. By effectively combining the carrier phase observations of dual GPS channels, it can achieve heading accuracy of up to 0.1 degrees (2M) with high measurement reliability, and the directional results do not drift over time. Suitable for navigation, positioning, speed measurement, orientation, and precise timing of various aircraft, vehicles, ships, and other moving carriers.
