GPS Receivers?

An Anonymous Coward asks: "I need a GPS receiver for some field research, and am having some trouble finding one that meets my requirements. I need to have the coordinates and time recorded once per second for an extended period (12+ hours) with a decent accuracy (5 meters or so). Ideally, I'm looking for a device which will record real-time to my Dell notebook (running Windows XP), but I'd be okay with one that recorded into it's own memory as long as I could download to my Dell easily and: a) it has enough memory to save a days worth of data or b) it will save about an hours worth of points but is cheap enough that I can get two (so I can tag-team them). I'm working on a research budget, so the solution has to be under $800 (but less is better, or course). I thought a PCMCIA card receiver might be a good solution, but it seems like the stand-alone units have more to offer, so I'm open to either option."

NMEA data is insufficient to increase accuracy.
Nothing wrong with NMEA data for typical usage. I've used it for moving map displays, etc. But, to increase accuracy you need access to significanly more detailed information, which is not available from units other than Garmin for less than $1000+.

NMEA data is not the same as RINEX.
