DGPS

[Guest tak1]

Aside from WAAS, do any of you guys use a differentially corrected GPSR? I've noticed that many of you have money to burn, thus you have 2 or 3 receivers. If you are all so worried about accuracy why not buy a differential beacon and be done with it. This is a sure way to get your 6 to 9 feet EPE.

Having two or three GPSR's is not so much about greater accuracy. It is more about different features and having lots of gadgets.

tak1, generally you will find non-WAAS diff units in a fixed mount application like boating and aviation because of the need to have a second antenna. I am of the opinion that non-waas differential is not practical in a handheld, which is what you find many of the readers here have. I would also think that additional accuracy is not the reason that people on this forum have multiple units. I'd guess that they just don't get rid of the old ones when they upgrade, then use the old units as backup.

 

If you'd like more info on fixed mount diff. applications, try posting a question here. Many fishermen/boaters depend on precise units to re-find underwater structure and combine the repeatable accuracy capabilities of LORAN-C and diff. GPS.

Wouldn't getting a dGPS unit to add to your gps be more expensive then buying a WAAS gps?

Normally does especially if it's an external standalone beacon but as with most things GPS it really depends on the application and comparing the requirements against the expense.
