Humminbird has for several months now been on the market with a GPS receiver with an integrated heading sensor. They call this their model AS GPS HS. You can see the device at

and you can download the user manual from

http://store.humminbird.com/media/document/GPS_Manual_5314784EN_B.pdf

The AS GPS HS is priced at $199. It appears to offer two outputs: one output is in the proprietary Humminbird network form and connector style; a second output is provided as a NMEA-0183 serial data connection. The first output limits the application of this device to Humminbird networks and Humminbird chart plotters, but the standard NMEA-0183 output makes the device more universally applicable. However, you need a Humminbird chart plotter to configure the device to use the NMEA-0183 output and set the serial port parameters. Also, the device appears to take its power from the Humminbird network connection. This also limits its usefulness outside of the Humminbird world of devices.

The device is described as only being able to receive the GPS system satellites and the usual augmentation systems of WAAS (for North America), EGNOS (for Europe), and MSAS (for Japan). It does not appear to be capable of using the GLONASS constellation of satellites.

There are instructions that talk about setting the baud rate to 38400 and connecting the NMEA-0183 output to an autopilot.

OK, how does this compare to the Lowrance Point 1? We gave it a pretty good look here

I'd lean to the Poit 1 since it's a NMEA 2000 compatible device.

Comparing the Humminbird AP GPS HS to the Lowrance POINT-1, it looks to me like for a non-Humminbird application the Lowrance device is the winner, because:

--POINT-1 runs on standard NMEA-2000
--POINT-1 is a GNSS receiver that can use GLONASS satellites to add more possible pseudo-range solution options
--POINT-1 is 10-Hz capable

I don't see the Humminbird AP GPS HS to be of much use outside of the Humminbird realm of products. The AP GPS HS does give the Humminbird line of chart plotters a nice upgrade by providing a heading sensor at low cost.
