Don, I have owned a number of GPS receivers over the years, and I feel that the Garmin GPS76 is about the best non-professional GPS receiver I have used. It doesn't have the centimeter-level accuracy of my Ashtech survey-grade receiver, but it comes about as close as you can get without post-processing of differential data.
The main features that the GPS76 (not the same as the GPS76MAP) has are a fairly large display, an external antenna jack, a power/data connection, and WAAS (Wide-Area Augmentation System) capability. Don't even think about buying a GPS receiver that doesn't have a jack for an external antenna. The power/data connection allows me to record position every two seconds on a GPS Datalogger, along with the date, time, speed, heading, and elevation. This is great for charting rural roads, bike rides, and off-road travels. When used with a high-end mapping program like Ozi Explorer, it is an extremely capable tool. My GPS76 is mounted in my SUV using an articulated mount from RAM- very rugged and handy. When used with a magnetic (or permanently-mounted) remote antenna on the car roof, the GPS76 can achieve horizontal positioning errors below 3 meters in 3-D Differential Mode. That's very good for a unit that costs less than $500! 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Don Kupferschmidt Sent: Sunday, July 08, 2007 5:53 PM To: [email protected] Subject: [Repeater-Builder] GPS Navigational units Hi to the group, I've been following the acronyms thread - somewhat off subject but I learned a lot. So it appears that repeater-builder lets the authors deviate from the original subject matter. I guess that even though my subject isn't directly related to the topic of repeater building, it will probably have some good comments by the 3600+ list members. I need to buy a good GPS navigational unit for my work. There are the major players, like garwin and tomtom, to name a few. Can any one give me some good advice on what to buy? What's good, bad, indifferent out there? What are some good features that the units have that you have / like? Majority of good reviews win. I buy that unit. Don't let me down - I'm counting on you guys. TIA, Don, KD9PT [EMAIL PROTECTED]
