About the Course

High Precision GNSS using Post-Processing

Explore GNSS error sources and examine ways of mitigating errors in a highly practical course.

High-precision GNSS underpins the delivery of Network Real-Time Kinematic positioning services. It can also be employed for a variety of more precise surveying and engineering applications, such as high order control establishment and deformation monitoring, if the data are post-processed.

In this two day course, you will:

  • explore in detail the various GNSS error sources that inhibit precise coordinate determination
  • examine ways of mitigating these errors using additional data and methods available in post-processing mode.

We'll introduce error theory and provide ample opportunity for real-world practical analysis, using Leica Geo Office GNSS post-processing software. We've designed the extensive practical examples to reinforce the theoretical concepts. The examples rely on specially designed data sets, covering a wide range of real-world conditions and problems.

The exercises will help you to develop a feeling of processing accuracy and precision levels and ways of improving them, using the options offered by the software.

Who is the course aimed at?

The course is aimed at practitioners who are already familiar with basic GNSS and Network RTK, and provides a highly relevant follow-on course for delegates who have attended the three-day GNSS and Network RTK course.

Course dates
  • Thursday 2 - Friday 3 April 2020 (duration 2 days)

Course Outline

We always welcome questions from the participants and we may be even able to adjust the course flow to cover questions arising in discussion, if time allows.

The course topics include:

  • Drivers for use of CORS networks and post-processing
  • Getting, understanding, and working with CORS data and GNSS orbital products
  • GNSS processing and overcoming problems: practical exercises
    • Which type of orbit products do you need?
    • Accounting for antenna phase centre variations
    • Modelling ionosphere: what can go wrong with single-frequency data?
    • Ways of mitigating tropospheric errors: relative positioning and modelling the atmospheric delay
    • Understanding Ocean Tide Loading
    • What session duration is needed in different circumstances?
    • GNSS heighting
  • What do the solution quality indicators tell you? Can you always trust them?

Further Information

High Precision GNSS using Post-Processing

Although we provide a training data set, you are welcome to bring your own data sets in order to use them as additional examples in practical processing exercises. However, in order to make sure that the precious course time is spent most efficiently, we need to define some rules these data sets have to abide by:

  1. The data must be collected within Great Britain no earlier than four weeks and no later than two weeks before processing. These time limits are dictated by OS reference data availability on one hand and the readiness of precise orbital products on another;
  2. All the data must be accompanied by clear log sheets, showing:
    • the approximate location of the site
    • date and time of the start and the end of every session
    • the make and type of the receiver and antenna used, antenna height, GNSS (was GLONASS used?)
    • sampling interval and elevation cut-off angle used
    • any other notes that may be relevant to the session;
  3. The data must be in RINEX v2 format or you must be able to convert them to RINEX v2 on the spot;
  4. The data must be collected with sampling interval of 30 s, or reducible to this interval.
  5. The data should be collected using a receiver and an antenna listed in ftp://ftp.igs.org/pub/station/general/rcvr_ant.tab.

We cannot guarantee the success of the processing even if all the above conditions are satisfied. Examples of confounding factors are: insufficient length of the session, local sky view obstructions, and other site-related effects. However, a negative result can teach a lot about how to do and how not to do GNSS surveys and processing.

Course Materials

During the course, you will be able to access course materials electronically using the University Wifi. We suggest that you bring a laptop or tablet with PDF viewer if you wish to refer to the notes during the course. Please ensure that you make sure your electronic device is fully charged, as access to charging points may be limited within the lecture rooms.

Update to Course Content
