Figure 2 - InSight GPS 50-W Antenna Dimensions
This INSIGHT GPS 50-W is based on an ultimate 32 + 8 channels GPS
engine that delivers accuracy better than three meters by decoding
the GPS correction signals from the satellite-based WAAS (Wide Area
Augmentation System). The GPS engine, interface electronics and the
passive antenna are enclosed inside the water-proof plastic housing.
This provides advance state-of-the-art GPS performance in an easy-
to-use package.
