  • [GPS] Pharos vs GlobalSat ?

    More specifically:
    Pharos iGPS-500 vs GlobalSat ND-100

    People's opinions, though a review wouldn't hurt. I don't think phoronix has ever reviewed GPS products.

    This is what I have
    . 2 grams lighter (how much is a gram?)
    . newer NMEA version (3.1 vs 3.0)
    . better linux reviews
    . "looks" (picture) solid. American made I think.

    . supports two more NMEA sentences (lat. & long. + velocity vector). However, these can already be deduced (via computer) from other sentences.
    . 2 dBm more sensitive
    . 28 more channels (doesn't matter though, only ~10 NAVSTAR satellites in the sky at a given time, so)
    . power requirements are slightly less (more in the range of usb)
    . supports EGNOS (European) as well as WAAS (American)
    . weird baud rate despite data refresh rate similar to competitors. (gpsd compatible though)
    . First revision firmware has a date issue. Fixed in the second revision.
    . "looks" like a usb stick. Everyone knows how fragile those things are inside
    . unknown. zilch. nada. no reviews. Taiwanese company, though (I think).

    The gpsd compatibility page reports similar interoptability for both devices. The iGPS-500 isn't marked as having gpsd automatically started by udev, but that could be simply an oversight. I also couldn't find any information comparing the SirfStar3 e/lp with the M-Star MSB2122. I guess I'm simply looking for first-hand reviews before buying.
