Appropriate for military, civil and maritime communication use; either on control centers or coastal stations.
The CN-520-A antenna switching is designed to direct different radiofrequency signals between different transmitters and its antenna.
Applicable in INVELCO’s Navtex system to operate with 1, 2 or 3 transmitters in transmissions of 3 frequencies.

NAVTEX REMOTE CONTROL
The GX-400-A is the autonomous unit for the automatic/manual management of Navtex transmissions in 490 / 518 / 4209.50 KHz.
This unit is located in the transmissions centre and will be remotely run by the Navtex operation program that will conveniently update the information for the Navtex automatic/manual broadcasts transmissions.
It will be done by means of Ethernet communication channels (from 1 to 3 channels). When using more than one Ethernet channel, there is redundant communications
The unit has the capacity of monitoring the NAVTEX transmissions by using an additional, an auxiliary NAVTEX receiver.
The unit can also be configured to run a MF-HF Invelco transmitter for the automatic management of the Navtex transmission frequencies.
Its functional structure is based on the use of a SBC (Single Board Computer) in a of 19″.
Navtex Transmission Managing Software
The Navtex transmissions manager allows the maintainance of the programmed transmissions in 518KHz and 490KHz configuring them according to the needs.
As a difference from other versions, once a Navtex is modified or created, it is updated to a remote equipment located in a transmitter station. We, therefore, obtain Navtex transmissions even if the communication between both equipment is cut.
The communication with a remote equipment is done simultaneously through two communication lines (Ethernet and Modem connection), assuring the information arrives to its destiny. The state of such lines stays reflected by means of signalings in the main panel.
During the transmissions, the Navtex manager receives from the transmitter centre the Navtex monitoring in the remote receiver allowing therefore the maintenance of the data synchronization with the remote equipment located in the transmitter station.
Navtex Transmissions Managing Software
The Navtex transmissions manager allows keeping maintainance of the programmed transmissions of each coast. This can be configured, according to the needs, 518, 490 and 4209.5KHz.
The difference between the previous versions, once the Navtex has been created or modified, is that it is updated in the remote equipment (GX-400-A). This equipment is located in the transmitter station and therefore, although the communications between both equipments is interrupted, we ensure the Navtex transmission.
The communication with the remote equipment can be done, simultaneously, with up to three communication channels (Ethernet connection, Modem, GSM), ensuring therefore, that the information arrives to it’s destiny. The state of such lines stay reflected by means of signallings in the communications panel.
During the transmissions, the Navtex manager receives from the transmitter centre the Navtex that are monitored in the remote receiver. This allows keeping a synchronization of the data with the remote equipment located in the transmitter station.
