2J Antennas has announced the launch of its new range of high-precision, low profile active external antennas and passive internal ceramic antennas featuring superior precision, greater bandwidth, and an advanced signal design catering to GPS, GLONASS, BeiDou, Galileo, IRNSS and SBAS navigational technologies.
They are designed for demanding GPS applications that require centimetre-level accuracy by combining the Precise Point Positioning (PPP) of L1 and L2 or by combining L1 and L5 bands with Real-Time Kinematic (RTK) satellite navigation.
By using the L5 signal in combination with existing civil GPS bands, the user can benefit from a more accurate location system. The Satellite-based Augmentation System (SBAS) delivers correction data such as satellite position errors, clock/timing errors, and estimations of degradation parameters - making it ideal for civil aviation safety-critical applications.
The antennas operate with low power consumption whilst exhibiting high efficiency within 1176 MHz (L5), 1227 MHz (L2) and 1561-1606 (L1) MHz frequencies.
External active antennas are ideal for external environments where longer remote cable runs are required. Typical applications include land and hydrographic survey applications, navigation, aviation, unmanned aerial vehicle navigation, agriculture, and safety critical systems.
The new antennas are available in range of sizes and with a variety of mounting options, and they are fully customisable with the option of additional connector types, cable lengths, and cable types.
The antennas are compliant with complete IP67 and IP69 ingress ratings - providing maximum protection against dust and water.
The ground plane independent design allows these external antennas to be installed securely on a wide range of surfaces without restrictions.
