GNSS In


Port for connecting an external GNSS antenna. GNSS antenna can be either active or passive.

The power supply voltage of the active antenna is 3.3 V. The port is equipped with current consumption monitoring circuits to detect short circuits and antenna failure.


GNSS Output


GP-Probe DIN L1 is equipped with a GNSS output port that is connected to the GNSS input if the probe does not detect interference or GNSS signal anomaly. 

If interference/anomaly is detected, the port is disabled by a built-in RF relay. To combat powerful fake GNSS signals, the probe is equipped with a built-in gnss jammer that additionally blocks powerful fake signals leaking through the relay.



Power Port


The GP-Probe DIN L1 is designed for a power supply voltage ranging from 12 to 48 volts. It is possible to connect two independent power supplies.



PPS Input/Output

The GP-Probe DIN L1 has a PPS output coming from the built-in GNSS receiver. The pulse is generated only if the status of the GP-Probe DIN L1 is "Normal".


The GP-Probe DIN L1 has a built-in PPF phase difference measurement module. When an external pulse source, such as a time server, is connected to the "PPS In" port, the GP-Probe DIN L1 determines the phase difference every second and sends the data to GP-Cloud. If a specified threshold is exceeded, GP-Cloud sets the probe status to "PPS Offset".

The "PPS In" port supports low-voltage PPS signal sources.



Relay Terminal

Integrating GP-Probe into existing infrastructure is made simple with the use of a relay. The relay's behavior can be configured through the web configuration panel. If interference is detected, the relay will switch, making it easy to control external equipment.

The relay has three pins:

• C – common wire

• NC – normally closed

• NO – normally open



RS-232

The port is intended to control external equipment with an embedded LUA scripting engine. The sent commands, as well as the port operation modes, are determined by a script developed using the LUA language.

LAN


The LAN port has a standard 10/100BASE-T RJ45 interface pinout. POE power supply is not supported.
