• Possible usage in mobile applications
• Including 40 dB Multi GNSS L1 antenna and 20 m pre-assembled Belden H155 cable

The board GNS181PEX is designed as a low profile board for computers with PCI Express interface. The rear slot cover integrates the SMA antenna connector, a BNC connector for modulated time codes, a 9pin D-SUB male connector and four status LEDs (2mm light pipes). With this standard height bracket you can use the D-SUB connector for I/O signals like RS-232 - PPS and PPM and you can use this interface for firmware updates.

The GNS181PEX is delivered including a low profile bracket. You can mount this part instead of the standard bracket, to run the GNS181PEX in computers with smaller housing (e.g. 1U server).

The integrated GNSS receiver requires an external antenna. It can be configured to use GPS, Galileo, Beidou and GLONASS. The configuration allows the user to select one of these sources to be used exclusively or a combination with up to three of these sources:

• GPS
• GLONASS
• BeiDou
• GPS + GLONASS
• GPS + BeiDou
• Galileo
• GPS + Galileo
• Galileo + GLONASS
• Galileo + BeiDou
• GPS + Galileo + GLONASS
• GPS + Galileo + BeiDou

Satellite receiver for mobile applications:
The GNSS timing board is designed for operating in mobile environments like cars, trains or airplanes. An optimized active GNSS L1 antenna RV-76 with 10 meters coax cable RG-58 for operation in mobile environment is still available.
