{"title":"RTK Torch GNSS Base/Rover Surveying Device","handle":"sparkfun-rtk-torch","url":"/products/sparkfun-rtk-torch","description":"Built for field surveying, this heavy-duty RTK unit combines a multi-band GNSS receiver, internal antenna, battery, Bluetooth, WiFi and a 915MHz LoRa radio in a rugged enclosed design. It is intended to make Base/Rover setup straightforward while handling rough use across varied environments.Galileo HAS support lets the Torch achieve &lt;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 &lt;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 - Protected from water up to 1 metre for 30 minutes.Internal antenna: L1/L2/L5 with ≥2.3dBi gain.Internal battery: LiPo 7.2V 6.8Ah 48.96Wh with fast 10W charging.Run time: 26+ hours on a full charge.Control: Single push button control.Weight: 428g (0.94 lbs).Dimensions: 71 x 71 x 147mm (2.8 x 2.8 x 5.8in).GNSS receiver: UM980.GNSS channels: 1408-Channel concurrent reception of GPS, GLONASS, Galileo, BeiDou, QZSS.GPS: L1C/A, L1C*, L2P(Y), L2C, L5.GLONASS: L1, L2.Galileo: E1, E5a, E5b, E6*.Beidou: B1I, B2I, B3I, B1C, B2a, B2b*.QZSS: L1, L2, L5.SBAS: Supported.Horizontal accuracy autonomous: 1.5m.Horizontal accuracy DGPS: 0.4m.Horizontal accuracy RTK: 0.8cm + 1ppm.Vertical accuracy autonomous: 2.5m.Vertical accuracy DGPS: 0.8m.Vertical accuracy RTK: 1.5cm + 1ppm.Max altitude: 18km (11 miles).Max velocity: 515m/s (1152mph).Band support note: Bands marked with * are only supported by specific firmware.Bluetooth® transceiver: ESP32 WROOM.Microprocessor: Xtensa® dual-core 32-bit LX6 microprocessor.Clock frequency: Up to 240MHz clock frequency.Flash storage: 16MB of flash storage.PSRAM: 2MB of PSRAM.Internal SRAM: 520kB internal SRAM.WiFi transceiver: Integrated 802.11 BGN WiFi transceiver.Bluetooth®: Integrated dual-mode Bluetooth® (classic and BLE).915MHz LoRa radio: STM32WLE.LoRa microcontroller: Cortex-M4 microcontroller running at 48MHz with built-in LoRa radio.RF front end: 900MHz SKY65313-21 RF front end 1 Watt amplifier.Multipoint support: One Base to multiple Rovers.FHSS support: Supports FHSS 902 to 928MHz.Compliance: Compliant in North America and South America.Suitable for survey, mapping and GNSS positioning workflows where a portable RTK Base/Rover or temporary base setup is required.","vendor":"SparkFun","product_type":"RTK GNSS Receiver","in_stock":true,"options":[],"variants":[{"id":16012,"title":"Default Title","sku":"SF-GPS-25662","mpn":"GPS-25662","price":4510.35,"on_sale":false,"in_stock":true,"available_quantity":4}]}
