Data Sheet

JLink Lite allows the GNSS rover capturing of RTK quality data points where cell phone cover is poor. It provides a robust solution linking the field GNSS equipment to VRS network, where no cell phone cover is available.

Jlink Lite enables to surveyors to capture data points up to 13 km from where the nearest cell phone coverage is available. Embedded GPS L1 functionality allows using JLink Lite as standalone wireless network RTK field access point.

JLink Lite contains 1 W UHF Radio Transceiver with built-in quad band GSM/GPRS module. It access VRS network using TCP/IP protocols. It takes incoming data from the network, modulates it with GMSK, FSK, PSK or most spectrum efficient QAM modulation and transmits it at RF power output levels from 10 dBm up to 30 dBm operating in UHF frequency band (406 to 470 MHz).

The JLink Lite is also capable of receiving RF signal from remote UHF transmitter, and the data could be send over the cellular network using built-in GSM/GPRS module if such operation mode is selected.

The unit’s user settings can be changed through the CLI interface or through ModemVU. The output transmit power, receive signal strength (RSSI), antenna/feed line condition, and data decode performance will be transmitted online without application interruption.
