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

Listen Listen is an alternative to traditional DOT, NTRIP, CORS, and VRS networks, in addition, tightens Hrms & Vrms results, so you do not have to worry about interference from other rovers on your private network, never ending network downtime, cumbersome telescopic antenna setup, nor recurring service interruptions with existing RTK networks

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

Traditional UHF radios in most parts of the world are limited to 0.5 watt or 1 watt power output, which provides up to 1.5 mi single baseline range at best. Listen-Listen works up to 20 mi single baseline - Hrms & Vrms results will vary

Both intuitive and compatible with Carlson SurvPC 6.17 or newer versions, Listen Listen requires two simple setups in Carlson SurvPC for the base and rover. There are no extensive setup parameters required, unlike UHF communications

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 plans. Fixed or static IP address are not required. In addition, unlimited rovers can simultaneously connect to a single GNSS 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. Listen Listen NTRIP service is exclusive to Carlson GPS receivers and designed for RTK, not PPK drone surveying missions
