GLONASS GPS

GLONASS GPS
NAVIGATIONAL RECEIVER
CH-3700
• Navigational sensor CH-3700 is
multipurpuse equipment for users of
SNS, which is established in
integrated navigational systems. It is
destined for determination of current
coordinates, track angle, speed and
time to signals of SNS GLONASS and
of GPS NAVSTAR anywhere in the
world and at any moment of the time,
irrespective of the weather
conditions.
• It distributes navigational data by the
standard interface in integrated
navigational systems.
• Sensor is universal equipment and
has a developed interface which
guarantees junction with others
devices and systems.
• Built-in software allows to use sensor
CH-3700 for various aimes:
- guarantee of navigation;
- elaborating of adjusting information
for differential GNSS;
- output of hi-precision time mark over
time scale of UTC and UTC (SU).
