Fuentes de Corrección GNSS

Las operaciones GNSS son igual de buenas que la fuente de corrección que se use. Por eso, es importante que elija la opción adecuada a sus necesidades. Los sitios de obra podrían necesitar una estación base GNSS, mientras que para los más pequeños tal vez prefiera una fuente de corrección virtual.

  • Estación base Trimble GNSS

    gnsscorrex-basestationPara las obras de construcción más grandes y para aquellas que incluyen tanto posicionamiento en obra como operaciones de control de maquinaria, le recomendamos instalar el receptor modular Trimble SPS855 GNSS como estación base permanente o semipermanente.

    Para obtener más información sobre el tipo de antena externa a elegir para su estación base, visite la página web de las antenas Trimble GNSS o bien, comuníquese con su distribuidor de tecnología SITECH®. 

  • Network RTK

    Trimble VRS is a Network  Real-Time Kinematic (RTK) subscription service delivered via the Internet over a cellular network. Like the MSS services, VRS is ideal for construction sites where it is not practical to set up a base station, such as sites where there is no machine control or for initial reconnaissance tasks where a base station is not yet established.  VRS does require an Internet connection at the rover. Utilizing Trimble VRS technology, centimeter level accuracy is available on demand, anywhere within the reference station network. It's highly cost effective and efficient, super convenient, simple to use, and, best all, it's always on.

    VRS Now is a Trimble operated VRS network. To select the service that best suits your needs, please view the Trimble Positioning Services web site.

  • Trimble xFill

    Trimble xFill runs seamlessly in the background, automatically bridging the gap if a user's RTK or VRS correction source is interrupted due to cellular signal disruption or loss of UHF radio connectivity. Trimble xFill is a satellite-delivered service that will maintain RTK precision for five minutes after the loss of an RTK correction stream.

  • Servicio de Estación Base por Internet (IBSS)

    tcc-ibssEl Servicio de Estación Base por Internet (IBSS) de Trimble transmite correcciones cinemáticas en tiempo real (RTK) desde su estación base por internet mediante Wi-Fi o una red de telefonía celular. Eso facilita y hace más económico el uso de GNSS de alta precisión para posicionamiento de sitios o control de maquinaria en obras de construcción. 

  • Mobile Satellite Services (MSS)

    Satellite-based GNSS correction services include Trimble RTX and OmniSTAR. MSS delivers real-time and highly reliable positioning services for land-based construction sites worldwide, 24 hours a day, 365 days a year.

    MSS is delivered via geo-stationary L-band satellites, the signal is received at the GNSS rover by the Trimble GNSS antenna or GNSS Smart Antenna, so there is no requirement for a UHF radio or cellular network connection.

  • MSK Beacon

    MSK Beacon refers to a DGNSS or DGPS reference stations maintained mostly by the International Association of Marine Aids to Navigation and Lighthouse Authorities (formerly IALA) which transmit a free differential correction service on the 300 kHz band. Trimble marine GPS/GNSS receivers with the appropriate MSK capable antenna can use these corrections at no cost for sub-meter positioning.

  • Satellite-Based Augmentation System (SBAS)

    The Satellite-Based Augmentation System (SBAS) is based on GNSS measurements from accurately-located reference stations deployed across an entire continent. The differential corrections and integrity messages are broadcast over a continent using geostationary satellites as an augmentation or overlay of the original GNSS message. Systems in place are WAAS (USA), EGNOS (Europe), GAGAN (India) and MSAS (Japan) which deliver corrections at no cost for sub-meter positioning.
