  -LRD (Long Range Download) - the most popular GPS-UHF loger in our offer with radio download option. In comparison to simple UHF models it gets solar charging as standard thus in addition to battery used data might be downloaded within few kilometres range from base station.

Main Features of LRD models:
- Data access: base (ground) station and PC application;
- UHF download range in line of sight: 4000-6000m;
- UHF communication: bidirectional and digital telemetry;
- Memory 30 000 GPS positions;
- Solar charger;
- Voltage control: Optional automatic GPS interval control, standby < safe voltage to protect battery;
- Data formats: .csv, .kmz (Google Earth);
- Switching on/off: magnetic & software switch, 1 colour LED communication.
