FAQs

What is the PRECISE PL2 and what is it used for?

The PRECISE PL2 is a high-power external UHF radio designed to extend the communication range of RTK Rover systems. It enables stable differential signal transmission in challenging environments where built-in radio range may be insufficient, and integrates seamlessly with PRECISE RTK receivers to enhance positioning accuracy and efficiency.

What frequency range and output power does the PL2 support?

The PL2 operates across 410–470 MHz UHF with selectable 12.5 kHz or 25 kHz channel spacing. Output power is selectable at 10W or 30W (at 13.5V input) with ±1dB stability — suitable for both standard range and long-distance communication across large surveying sites.

What data rates does the PRECISE PL2 support?

The PL2 supports air data rates of 4800, 8000, 9600, 16000, and 19200 bps using GMSK and 4FSK modulation. Receiver sensitivity is better than −116 dBm at BER 10⁻⁵ at 9600 bps, ensuring reliable data transfer even under weak signal conditions.

What are the power and interface requirements for the PL2?

The PL2 requires 10.8–15V DC input power. It features a TNC antenna interface with 50-ohm impedance and a 5-pin data interface. Its operating temperature range is −40°C to +85°C, making it suitable for outdoor use in varied climates.

Is the PRECISE PL2 compatible with all PRECISE RTK receivers?

The PL2 is designed for seamless integration with PRECISE RTK systems. It functions as a standalone external radio module that connects via the data interface port and UHF antenna connector, extending the communication range of any compatible RTK rover in your workflow.
