1. SMART DGPS RECEIVER
This SMART DGPS RECEIVER is based on a ultimate 32 + 18 channels GPS engine that
delivers accuracy better than three meters by decoding the GPS correction signals from the
satellite-based WAAS (North America Wide Area Augmentation System), EGNOS (Euro-
pean Geostationary Navigation Overlay Service), MSAS (Asian Multi-Functional Satellite
Augmentation System), GAGAN (Indian Geoaugmented Navigation). The GPS engine,
interface electronics and the passive antenna are enclosed inside the water-proof plastic
housing. This provides advanced state of the art GPS performance in an easy to use
package.

1.2 SOFTWARE INTERFACE
The GPS products interface protocol design is based on the National Marine Electronics
Association's NMEA 0183 Standard For Interfacing Marine Electronic Devices. These
standards are defined in "NMEA 0183 Version 3.01" (for more information see NMEA,
www.nmea.org).

1.3 MECHANICAL CHARACTERISTICS & MOUNTING
1.3.0 Installing
Choose a location for the antenna that has a clear view of the sky. Ensure there are no major
obstructions or fixtures in the immediate proximity to the antenna. The antenna relies on
direct “line of sight” satellite reception. If you are unsure that the chosen location is suitable
it may be advisable to mount the antenna in a temporary manner to verify correct operation.
The thread used on the antenna (1", 14 TPI) is an industry standard thread used on a wide
range of mounting brackets, including the swivel joints commonly used for angled surfaces.
Due to the manufacturing process of these mounting brackets you may see that there is
some slop when tightening down the antenna to the bracket. This is of no concern however
as the antenna must be tightened until the antenna stops rotating on the antenna mounting
bracket.

The antenna design also allows for easy flush mounting.
1. Apply the adhesive mounting template sheet in the area that was verified to receive
satellite signal well.
2. Then, following template instruction, drill a 0,78" (20mm) hole and three 0,13" (3.2mm)
holes.
3. Remove the template and let the cable go through the central hole.
4. Apply a small coat of RTV to the underside of the antenna.
5. Place the antenna and then screw it with the three M3 screws.
Another method:
1. Apply the adhesive mounting template sheet in the area that was verified to receive
satellite signal well.
2. Then, following template instruction, drill a 0,78" (20mm) hole.
3. Apply RTV silicone to the underneath side of the antenna and glue the antenna to the
flush mounting area.
