Explosion-proof GNSS receiver

Explosion-proof GNSS receiver (for GPS, GALILEO satellites) with integrated data logger.

The Ex GNSS receiver device is a 72 channels receiver for GNSS signals emitted by GPS, GALILEO satellites, that enables it to determine the position of the receiver, its speed as well as the current time. The latitude and the longitude at any time can be recorded on the internal flash memory, in order to build a data history that can be retrieved later on over USB.

The device can provide its positioning data at 10Hz, with a resolution of 10-6 degrees, e.g. 10cm approximately. The expected absolute accuracy with clear satellite view is about 2.5m.

This device uses an external active antenna, using a U.FL (IPEX) connector. A small patch antenna (25x25mm, without enclosure) with a 10cm cable is included with the device. You can also use any other active GPS antenna, for instance a larger antenna in a waterproof enclosure with a long cable, using the U.FL to SMA adapter.

This device can be connected directly to an Ethernet network, to a WiFi network and to a GSM network using special adapters.

Note: To use the Ex GNSS receiver in a hazardous area, the Ex GNSS receiver must be protected to at least IP 65, so it must be placed inside the enclosure.

Ex GNSS receiver don’t require any special drivers or software. Compatible with Windows, Mac OS, Android and Linux and easy to drive from a maximum of programming languages.

The Ex GNSS receiver is connected through an industrial USB 2.0 connector to an intrinsically safe barrier Ex USB 2.0.

The Ex GNSS receiver have a “hot-plug” function which allows them to be connected and disconnected without stopping, shutting down or rebooting the system.
