GISUY Surveyor
The GISUY Surveyor is a multi-constellation single frequency receiver that targets land surveying and vehicles tracking activities. It has a sub-meter accuracy (CEP accuracy < 2 meters), suitable to open sky scenarios (e.g. agriculture) or environments with “weaker” GNSS signals, such as forests and urban areas. The receiver’s positioning is typically acquired via Bluetooth using smartphone applications, such as GPS Waypoints or other applications.
The receiver uses ublox M8 chipset, capable of acquiring positioning from GPS, GLONASS, Galileo and BeiDou satellite systems and supporting both Standard Positioning Service (SPS) and Satellite-based augmentation (SBAS). The three built-in configurations available are:
1) SBAS GPS-GLONASS (default): adequate for open sky environments, reaching better vertical precisions;
2) SPS GPS-GLONASS: adequate for areas with weak signals since it enables faster fixes and better horizontal positions;
3) SPS GPS-GLONASS-GALILEO: targets also weak signal environments, enabling faster fixes with 3 concurrent constellations.
The receiver comes with an internal patch antenna or optionally with SMA connector for external antennas (handheld or vehicle mounted). It is powered via USB and includes an internal battery that provides autonomy for outdoor activities, as well as ensures backup power on vehicles tracking (when the engine battery circuit is off). The Bluetooth and USB serial interfaces deliver standard NMEA sentences.
Firmware and Applications
The GISUY Surveyor firmware (version 2.7) can be configured via serial console (Bluetooth or USB). Although it also has a user-friendly web configuration, this interface is only accessible after configuring the Wi-Fi connection via console. The default configuration comes with NMEA 0183 v4.10 that can be changed to v2.3.
Since the receiver uses standard NMEA sentences, it can be used by both mobile and desktop applications, using a Bluetooth or USB connection. The mobile applications using Bluetooth (such as GPS Waypoints) are the most typical ones but the existing interfaces are versatile for multiple applications and business sectors.

The Surveyor is an IoT device only available for quoting and ordering via email with an estimated delivery time of 2 weeks.
GISUY Safety Monitoring
The GISUY Monitoring configuration aims to monitor GNSS signal quality, that is crucial on safety critical businesses, such as aviation. It is used to monitor fixed positions errors and GNSS signal interferences for specific environments.
The receiver has similar hardware as the Surveyor but uses an external antenna and a permanent power supply. It is typically powered and connected via USB to laptops and single board computers (e.g. Raspberry Pi) running monitoring applications. It comes with 3 built-in configurations, reconfigurable using the serial console: 1) SBAS GPS (approved in aviation); 2) SPS GPS (approved in aviation); 3) SBAS GPS GLONASS (typical in transports).
Applications
The monitoring applications typically identifies accuracy levels and signal quality where processing can be performed offline or online. The receiver can be integrable with SWAIR product for getting extended metrics.
