Una buena forma de involucrarse en el proyecto OpenStreetMap es cargar las trazas GNSS (GPS, Galileo, GLONASS, BeiDou/COMPASS, etc.). Generada por tu receptor de satélite o teléfono móvil, la traza típica es un registro de tu ubicación cada segundo o cada metro. Conviértela a formato GPX si no lo hace por ti automáticamente. Los datos recopilados se pueden mostrar como un fondo de líneas finas o pequeños puntos dentro del editor de mapas. Estas líneas y puntos se pueden usar para ayudarte a añadir características del mapa (como carreteras y senderos), similar al trazado mediante imágenes aéreas.

Thinking of getting a GPS receiver to add data to OSM? These reviews are here to help. If you think about other mapping related hardware too, look at the Hardware Guide.

If you buy a GPS unit via any of our retail partners then up to 10% of the purchase price will be donated to OpenStreetMap. This helps to help keep our servers running. See the Shop for details.

The correct term is GNSS (Global Navigation Satellite System), though the most common system GPS have become the name most people use (if you go to your local shop and ask for a GNSS, the clerk will probably not know what you mean).

Legend for the summary tables

Units are listed alphabetically.

Type can be:

  • Data Logger: the GNSS includes an automatic geographic position logging system with extraction possibility to another electronic device
  • Recreational: the GPS receiver can either simply deliver a geographic position for another device or display it on a simple screen with no navigation facility.
  • Navigator: the GNSS includes a screen with maps and software for turn-by-turn navigation assistance
  • Mobile Phone: the GPS is included in a mobile phone device
  • Smartphone: probably the most abundand GPS device these days
  • Professional GNSS: the GNSS is designated for massive or accurate geographic survey. Many such devices also combines the various GNSS technologies, such as combined GPS/Glonass receivers and evaluate the different carrier signals.

Glonass is also available as a backup/augmentation in some GPS receivers, but at the moment not available as standalone handheld units.

Storage can be:

Internal MultiMedia (MMC) Secure Digital (SD) None
Specify the capacity , or , , or none

Common GPS chipsets are:

  • SiRFStar I, II, IIe, IIe/LP, IIt, III
  • SiRFLoc
  • SiRFXTrac
  • Nemerix
  • RFMD
  • MTK
  • Sony Solution
  • u-Nav + iTrax 3rd Gen
  • Atmel Antaris 4l
  • u-blox
  • Ublox
  • Xemics
  • HP6515 AGPS
  • Skytraq Venus 5
  • Skytraq Venus 6

Methods of DGPS correction / Augmentation can be

  • SBAS (WAAS, EGNOS, MSAS), Beacon, NTRIP, Direct IP, IALA are free services, with various coverage.
  • Spotbeam, Inmarsat, Veripos, HP/XP are semiglobal services but requires licenses and are not likely in handheld units.
  • Corrections can be transmitted as proprietary formats, single station corrections, or 'RTCM' format correction list. Some receivers might use RTCM as identifier for corrections, but the source than is one of the systems mentioned above.

Alternative forms of GNSS are named according to the promoters of the satellite constellations: the existing GPS system properly named, Glonass, Galileo (still in deployment), and BeiDou (COMPASS). On devices equiped with tuners capable of hearing multiple constellations, it may be possible to get more precision and better coverage than what can be done today with just the GPS alone (some newer constellations will provide additional services not limited to one-way geolocating, such as Argos-style emergency signals for search and rescue).

AGPS is an abreviation for Assisted GPS, and is usually an enhancement for GPS-enabled cell phones. It allows receivers quicker startup time, as well as continuing to give positions with weak or missing satellite data.

Connectivity can be achieved by:

WiFi Bluetooth IrDa NFC/RFID USB PS/2 Serial RS232
)))

GNSS: Global navigation satellite system (GNSS) that can be received. Possible values are

  • GPS
  • GLONASS
  • Galileo
  • BeiDou

Measured DRMS accuracy: Horizontal RMS (root mean square, or Distance Root Mean Square, DRMS) deviation of the measured position from the true (or long-term averaged) position. Should be assessed by measuring a point cloud under good visibility conditions for at least several hours. Not to be confused with the DOP accuracy estimation, which may not match the actual obtained accuracy.

Dual-frequency: If the device can use two frequencies for accuracy enhancement, such as E1/E5a for Galileo or L1/L5 for GPS.
