Ashtech Reliance CG Beacon / GPS Receiver

Where Are You Going To Receive A Coast Guard Beacon Signal ?

It is my understanding that some Ashtech Receivers may not have had memory. I have an Ashtech Reliance SCA 12 that I use as a straight receiver. It has internal memory. I also have the controller which I do not use. I simply turn it on and off. The combined CSI beacon antenna which includes the beacon and gps antenna has never been tested for precision. I was fortunate to find a standard SCA 12 antenna.

It is Y2K compliant.

Paul,

I am looking to get into an affordable sub-meter system I can stream NMEA from. Between the Mississippi River and the Great Lakes, we have multiple site coverage over most of the State of Wisconsin.

Thanks for the info,

Matt

HemisphereGPS: MBX-4.
Real-Time DGPS Sensor, that will auto-tune the USCG/USACE - DGPS Beacons, output pretty much all NMEA standard messages into HYPack, Hyper Terminal, ESRI, etc...

CSI Wireless is now HemisphereGPS; CSI Wireless and SATLOC combined now = HemisphereGPS. Pretty much the only GNSS manufacturere that make this type of product these days.

The company I used to work for bought a new reliance system in 1999 with the coast gaurd beacon to make it submeter, so I'd think it was Y2K compatable if they were selling them new in 1999. We bought two and were told we could post process static sessions. We used it for a few weeks, and the boss returned it and exchanged it for a Locus system. If I remember correctly, the issue with the Reliance was the office software, which had static post processing capabilities, was JUNK, and was pumping out unreliable static results that even had the techs at APE stumped.

Don't Post Process With The Reliance Processor

I have used Ashtech Solutions for years. The newer GNSS Solutions also works.

I did some DGPS with a Reliance for a company I worked for. Later I used 3 ProMark 2s I then purchased to essentially do more precise work for them. A bit later they bought a Leica 1200 RTK setup and paid extra to get a DGPS setup that used the 1200 receiver. I bought their Reliance to use as a static only receiver with my other units.

It is good you are in an area with overlapping DGPS coverage, but given the increase in CORS locations you can get rather precise positioning with short static occupations with the receiver and a Virtual Reference Station base inside GNSS Solutions.
