It is intended to make Base/Rover setup straightforward while handling rough use across varied environments.Galileo HAS support lets the Torch achieve <50cm accuracy anywhere in the world without needing a corrections source. Tilt compensation helps capture points that are awkward to reach, such as up against walls or on uneven terrain, while the built-in LoRa radio can connect two Torch units over about 10 miles.The Torch can be used with PPP corrections, as a Rover, for baseless surveying, or as a temporary base. It includes 1 month of corrections via PointPerfect IP, with coverage dependent on location.The enclosure is fully waterproof to its IP67 rating, but it is not recommended for permanent outdoor mounting. Hardware documentation, firmware resources, receiver command references, product manuals and component datasheets are available from SparkFun.Features:Heavy-duty RTK design: Made to handle diverse environments and rough handling.Base/Rover setup: Provides a simple and straightforward way to set up a Base/Rover system.Galileo HAS: Allows the Torch to get <50cm accuracy anywhere in the world without needing a corrections source.Tilt compensation: Allows surveying points that would otherwise be inaccessible, like up against walls or on uneven terrain.Built-in LoRa radio: Allows two Torches to be easily connected over a distance of about 10 miles.PPP corrections: The Torch can be used with PPP corrections.Rover use: The Torch can be used as a Rover.Baseless surveying: The Torch can be used for baseless surveying.Temporary base: The Torch can serve as a temporary base.PointPerfect IP: Purchase includes 1 month of corrections via PointPerfect IP.Android support: Field Genius.Android support: QField.Android support: QGIS.Android support: Survey Master.Android support: SurPad.Android support: SurvPC.Android support: SW Maps.Android support: Vespucci.Android support: Any GIS software that supports NMEA over Bluetooth or TCP.iOS support: ArcGIS Survey123.iOS support: QField.iOS support: SW Maps.iOS support: Any GIS software that supports NMEA over TCP.Specifications:NGS calibrated: Antenna Phase Center (APC).APC L1: 131.7mm.APC L2: 126.2mm.APC average: 129.0mm.NGS calibration data: Available.NGS calibration data file: ANTEX.NGS calibration data file: ANTINFO.Overall device enclosure: Enclosed aluminium and plastic design IP67 -
