The Dual-frequency GNSS "GM PRO U" with SurPad 4.2 for Android works in frequency ranges L1, L2 has 184 channels for performing of surveying works, such as: stakeout, determining clear boundaries of areas, land surveying, field area measurement, stake out points, stake out lines, GIS survey, stakeout roads, cross-section measurement, slope staking, power line survey, height control and other functions.

❗️❗️❗️To obtain centimeter accuracy, you need to use RTK corrections.

GM PRO mini Series

The receiver has 184 channels for communication with satellites and works with most satellite systems and frequencies:

• GPS: L1 C/A, L2C
• GLONASS: L1OF, L2OF

• BeiDou: B1I, B2I
• QZSS: L1 C/A, L2C
• SBAS: WAAS, EGNOS, GAGAN, QZSS SBAS

Equipment:

• GNSS receiver GM PRO model U;
• Perpetual license SurPad 4.2;
• Charging cable;
• Cartboard packaging;
• Case for storage and transportation (Option).

Industries of use for the GM PRO model U dual-frequency GNSS:

• Surveying
• Cadastral work
• Construction support
• Machine control systems in construction
• Forestry
• Landscaping
• Utilities
• Precision farming

The main advantages of the GM PRO model U:

• Centimeter measurement accuracy;
• Fast initialization due to the presence of two frequencies;
• Flexible configuration for any GNSS RTK network;
• Carrying out stake-out using the GM PRO Dual-Frequency GNSS receiver is much easier than with the help of a total station: measurements can be made alone;
• GNSS receiver GM PRO works from 5V that gives the chance to power it from any external 5V battery or the Geometer Power Station;
• The perfect combination of reliability and cost.

RTK Method

The essence of the GNSS RTK method is to receive a satellite signal simultaneously by a mobile rover at a point and by a base station at a known static point. The base captures the difference between the computed and actual data and sends the RTK correction to the rover. The GM PRO kit provides flexible adjustment of corrections from any available network broadcasting corrections via the RTCM protocol. Geometer company offers an effective solution - connecting GNSS RTK receivers to an RTK signal from a network of base stations. You can subscribe to RTK (receiving RTK corrections to the receiver) for a different period: a month, three months, half a year or a year. Dual-frequency GNSS receiver GM PRO model U allows real-time geodetic measurements.

Support for NMEA Protocol

The GNSS RTK receiver uses standard NMEA messages, ensuring high compatibility with all types of software that support geolocation functions. This provides accurate and reliable coordinate determination.

Increasing Productivity

It is advisable to buy a dual-frequency GNSS RTK kit to significantly increase your productivity: with the help of satellite equipment you will be able to perform much more measurements alone than you would at the same time with a partner using optical equipment.

Professional Assistant of Surveyor

Measured object files can be used in any application thanks to built-in file export capabilities. You can export data to the following formats: CSV, TXT, KML (for Google Earth). Also, using the Agroprofile website, you can display a field map on top of Google Maps maps in separate layers, get complete information about each field.
