The NV08C-MCM is an integrated satellite navigation receiver. The device’s key feature is its ability to work with both global navigation satellite systems (GNSS) that have been deployed so far in the world – GPS and GLONASS. The GALILELO and COMPASS as well as SBAS systems are also fully supported.

The NV08C‐MCM device was developed for use in high volume applications

demanding low cost, low power consumption and uncompromised performance

such as:

in‐car and handheld personal navigation

asset and personal tracking

anti theft systems

surveillance and security systems

The NV08C-MCM offers high sensitivity and high performance of GNSS signal

acquisition and tracking combined with low power consumption and small size.

The assisted GPS/GLONASS/GALILEO and advanced power saving modes are

supported.

Multiple satellites available from GNSS constellations ensure higher availability

of navigation signal in urban canyons compared to any single constellation

solution.

For system integrator the NV08C‐MCM provides a variety of interfaces, flexible power supply options, power supply for optional active antenna. A very compact and complete GNSS receiver can be integrated on a low cost 2 or 4‐layer PCB with a minimal number of external passive parts.
