  • GPS Receiver and Equipment Selection

    Credits: 1 PDH

    PDH Course Description:

    Selecting the right GPS receiver for a particular project is critical to its success. Receiver selection must be based on a sound analysis of the following criteria: applications for which the receiver is to be used (e.g., static or dynamic, code or carrier), accuracy requirements, power consumption requirements, operational environment, signal processing requirements, and cost. GPS receivers range from high-end, high-cost, high-accuracy "geodetic quality" to low-end, low-cost, low-accuracy "resource grade" or "recreational" models. Moderate cost, meter-level accuracy "mapping grade" receivers are also available. Dozens of vendors produce GPS receivers and there are hundreds of models and options available. This course presents only a
    brief overview on GPS survey equipment and selection criteria.

    There are two general types of GPS receivers: Code Phase and Carrier Phase. Geodetic quality receivers process both code and carrier phases. References to specific brands, models, prices, and features in this course will be rapidly out dated. Current comparative information on GPS receivers and options is readily available in various trade magazines, such as GPS World, POB, and Professional Surveyor. Prior to initiating procurement, USACE commands are also advised to consult the Army Geospatial Center or other commands for technical guidance on GPS instrumentation options.
