Carlson Listen Listen

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

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 or constant downtime or maintenance issues with existing NTRIP networks.

Listen-Listen service is exclusively designed for Carlson BRx6+, BRx7, and RTk5 GNSS receivers. Carlson BRx6+ requires a AT&T or T-Mobile data only SIM card to facilitate internet connection. Competitor OEM GPS receivers are not compatible with Listen Listen.

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 30 mi baselines.

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 setup 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 RTK Mobile, AT&T, or T-Mobile data cell service. Fixed or static IP address are not required. In addition, multiple rovers can simultaneously connect to a single base setup.

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.
