a-GEO L300 RTK GNSS Receiver with 60 Degree IMU Tilt

The a-GEO L300 is a professional, survey-grade RTK GNSS receiver designed for high-precision positioning, land surveying, construction layout, mapping and other field measurement applications. It combines a 1408-channel GNSS board, IMU tilt compensation, 4G connectivity, an internal UHF radio and multiple survey modes in a compact magnesium-alloy housing.

The receiver is designed for land surveyors, construction professionals, civil engineers, mapping specialists, GIS teams, contractors and other users who need reliable centimetre-level positioning in the field.

The a-GEO L300 can be used for topographic surveys, cadastral surveys, construction setting-out, road and utility projects, control-point measurement, site surveys, earthworks, as-built documentation, GIS data collection and static GNSS observations.

Yes. The a-GEO L300 supports both base and rover operation. It can transmit or receive RTK corrections through its internal UHF radio or use internet-based correction services through its integrated 4G modem, Wi-Fi or a connected data controller.

The receiver supports Network RTK, UHF RTK, base and rover operation, static surveying and PPK workflows. The most suitable mode depends on the required accuracy, available correction service and conditions at the project site.

Yes. Its centimetre-level RTK positioning, rapid initialization and IMU tilt compensation make it suitable for setting out points, lines, levels and construction features without always needing to keep the survey pole perfectly vertical.

The a-GEO L300 supports signals from GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS and IRNSS/NavIC. Tracking several constellations and frequencies increases satellite availability and can improve positioning reliability in challenging environments.

The a-GEO L300 has 1408 GNSS tracking channels. These channels allow the receiver to track multiple signals from several satellite constellations simultaneously.

Under suitable satellite visibility, correction quality and field conditions, the specified RTK accuracy is approximately 8 mm + 0.5 ppm horizontally and 15 mm + 0.5 ppm vertically. High-precision static accuracy is specified at approximately 2.5 mm + 0.5 ppm horizontally and 5 mm + 0.5 ppm vertically. Actual results depend on the environment, baseline length, correction source and survey procedure.

The receiver is designed to initialize an RTK solution in less than 10 seconds under favourable operating conditions. Initialization can take longer where satellite visibility is limited, correction data is interrupted or signal multipath is present.

Its multi-frequency, multi-constellation GNSS technology can improve performance near trees, structures and other partially obstructed areas. However, dense canopy, tall buildings, reflective surfaces and severe signal blockage may still reduce accuracy or make it more difficult to maintain an RTK fixed solution.

The receiver supports commonly used correction formats including RTCM and CMR formats. This helps it communicate with a range of GNSS base stations, RTK networks and compatible third-party equipment, provided the selected radio protocol and correction settings match.

The integrated IMU compensates for the angle of the survey pole, allowing points to be measured or staked out while the pole is tilted. This makes it easier to reach building corners, walls, trenches, obstacles and other locations where holding the pole vertically is difficult.

The a-GEO L300 supports dynamic tilt compensation at angles of up to 60 degrees. For the best results, users should follow the field software instructions and ensure the receiver has a valid GNSS solution before recording a point.

The IMU is designed for fast initialization and calibration-free operation. It is also designed to resist magnetic interference, so users generally do not need to perform the traditional calibration routines associated with magnetic tilt sensors.

Yes. It has an integrated transmitting and receiving UHF radio operating from 410 to 470 MHz. The radio can be used to exchange correction data directly between a base and rover, subject to local radio-frequency regulations and compatible settings.

Supported radio protocols include AlphaTalk15, PCC EOT, Satel, SOUTH and TrimTalk450S. Compatibility with another receiver depends on both instruments using the same frequency, channel, protocol, correction format and related radio settings.

Yes. The built-in 4G modem can receive internet-based RTK corrections from an NTRIP or CORS provider. A compatible SIM card, mobile data connection and valid correction-service credentials may be required.

Yes. The receiver includes Wi-Fi and Bluetooth connectivity. Bluetooth can be used to communicate with a compatible survey controller, while Wi-Fi provides access to the receiver interface and can also support selected data-link workflows.

The receiver can be configured through its browser-based Web UI using a Wi-Fi-enabled phone, tablet or computer. The Web UI can be used to check receiver status, select the working mode, configure base or rover settings, manage communication links, update firmware and download data.

The a-GEO L300 supports survey and positioning data such as DAT, RINEX and NMEA output. Available formats and export options may depend on the selected operating mode, firmware and field software.

The receiver contains a 6800 mAh rechargeable lithium-ion battery. Typical specified operating times are up to approximately 12 hours in rover mode, 7 hours in base mode and 15 hours in static mode. Actual battery life varies with radio transmission power, mobile connectivity, temperature and receiver settings.

The receiver supports charging through its USB Type-C connection. The Type-C port can also be used for transferring data between the receiver and a computer. Use a suitable power supply and follow the charging instructions in the product manual.

The a-GEO L300 has an IP67 rating. It is protected against dust and is specified to withstand temporary immersion in water at a depth of up to one metre for approximately 30 minutes when all covers and connections are correctly secured.

The receiver has a rugged magnesium-alloy body and is specified to survive a two-metre pole drop onto concrete. It is also designed for vibration, humidity and demanding outdoor conditions. As a precision surveying instrument, it should still be handled carefully and inspected after a severe impact.

The specified operating temperature range is approximately -40°C to +75°C, with a storage range of approximately -55°C to +85°C. Battery performance, charging and field operation can be affected by extreme temperatures.

The receiver measures approximately 150 mm in diameter and 71 mm in height. It weighs approximately 1 kg, making it compact enough for mobile field surveying while retaining a rugged professional housing.

The receiver offers standard communication methods and data formats that can support integration with compatible third-party controllers, field software, base stations and correction networks. Compatibility should be confirmed for the required Bluetooth connection, NMEA output, correction format, radio protocol and survey workflow.
