# To measure FastStatic points

This type of point is measured in a FastStatic survey.

FastStatic surveys are postprocessed and do not need to be initialized.

1. Tap and select Measure / Measure points, or in the map, with nothing selected, tap Measure.

2. Enter the Point name and Code.

3. Enter a value in the Antenna height field and make sure that the setting in the Measured to field is set appropriately.
4. Tap Measure to start measuring the point.
5. When the preset occupation time is reached, tap Store.

   Receiver type | 4 SVs | 5 SVs | 6+ SVs
   --- | --- | --- | ---
   Single‑frequency | 30 min | 25 min | 20 min
   Dual‑frequency | 20 min | 15 min | 8 min

   No satellite tracking is necessary between measuring points. The occupation time counter for measuring a FastStatic point pauses when the PDOP of the satellites being tracked exceeds the PDOP mask set in the survey style being used. The counter resumes when the PDOP falls below the mask.

   The number of satellites required for measuring a FastStatic point depends on whether you are using GPS satellites only, BeiDou satellites only or a combination of GPS, BeiDou, GLONASS, Galileo and QZSS satellites. The following table summarizes the minimum requirements:

   Satellite systems | Required satellites
   --- | ---
   GPS only | 4 GPS
   GPS + QZSS | 3 GPS + 1 QZSS
   GPS + GLONASS | 3 GPS + 2 GLONASS
   GPS + BeiDou | 3 GPS + 2 BeiDou
   GPS + Galileo | 3 GPS + 2 Galileo
   BeiDou only | 4 BeiDou
   BeiDou + GPS | 3 BeiDou + 2 GPS
   BeiDou + GLONASS | 3 BeiDou + 2 GLONASS
   GLONASS only | N/A
   Galileo only | N/A
