LANTIME M300/MGR: NTP Time Server with integrated mobile GPS radio
clock
The Meinberg LANTIME M300/MGR Time Server uses a fully integrated mobile GPS reference clock as its
time source. A highly stable internal oscillator accurately bridges periods of interference or temporary loss of
reception.
The M300/MGR includes the Meinberg MGR170 timing receiver and is intended for use in mobile
applications onboard vehicles, ships, trains, or airplanes. The MGR170 GPS receiver supports different
dynamic platform models to optimize the navigation engine for the specific mobile environment and allows
more precise data averaging and a more accurate position solution.
The variety of possible output configurations makes this time server the premier choice for a broad range of
mobile time and frequency synchronization applications.
