Carlson Listen Listen

Carlson Listen-Listen is a cloud-based subscription service, which sends RTK corrections to your base and rover via cellular networks. 

Traditional UHF radios in most parts of the world are limited to 0.5 watt or 1 watt power output, which gives 1-2 mi single baseline range at best. With no restriction on data format or communication range, Listen-Listen works up to 20 mi baselines.

Listen Listen eliminates traditional DOT, NTRIP, CORS, and VRS networks, and shores up Hrms & Vrms results, so you do not have to worry about interference from other rovers on your private network.

Both easy-to-use and configurable with Carlson SurvCE or SurvPC field data collection software, Listen-Listen requires inputting just one 4-digit port number at the base and one 4-digit port number at the rover. There are no extensive parameters required, unlike UHF communication.

Listen-Listen requires an internet connection at the base and rover. SIM cards are the recommended solution to facilitate internet connectivity and reliability - compatible with AT&T or RTK Mobile data cell service. Fixed or static IP address SIMs are not required. In addition, multiple rovers can simultaneously connect to a single base using Listen-Listen.

Listen-Listen service is exclusively designed for Carlson BRx6+, BRx7, and RTk5 GNSS receivers. No other OEM GPS receivers are compatible.

Note: The Listen Listen NTRIP subscription option can be utilized with most RTK-capable drones to facilitate RTK corrections from your base GNSS receiver to your RTK drone.
