| |
 |
NovAtel's OEMV-2 is a backwards compatible, drop-in replacement for the OEM4-G2L. In
addition to maintaining features from the OEM4 receivers, this dual frequency board
features GPS+GLONASS positioning, NovAtel¡¯s AdVance RTK and use of the L2C signal
in a small, low-power card.
Ease of Integration
The OEMV-2 receiver is a drop-in replacement for the OEM4-G2L. Featuring the same commands and logs, this
board is designed to be backwards compatible, meaning fewer upgrades and faster time to market. In addition to
providing superior performance, the OEMV-2 card consumes less power than previous generation cards and is
compliant with the European Union¡¯s Restriction of Hazardous Substance (RoHS) directive, eliminating the need
for future hardware changes.
GLONASS
The OEMV Family of GNSS receivers offer GPS+GLONASS positions and measurements in real-time. The
GLONASS measurements are used in combination with GPS to provide more satellites for positioning in
challenging environments. The OEMV-1G, OEMV-2 and OEMV-3 receivers, and their enclosures are all
configurable as either GPS-only or GPS+GLONASS. The addition of GLONASS satellites to the positioning
solution enables users to work more often and increases availability of a position in obstructed sky
conditions.
GPS Modernization
NovAtel¡¯s OEMV-2 provides the user with performance and flexibility. Capable of tracking the new L2
civil signal, it provides stronger signal tracking and better cross correlation protection. Not only is the
L2C signal better for low signal strength applications, but having access to multiple signals allows
the user to select the one that is best suited to their needs.
Performance
When used for higher accuracy applications, the OEMV-2 RT-2 solution can provide real-time
centimeter-level positions at an update rate of up to 20 Hz, using NovAtel¡¯s
new AdVance RTK technology.
