Fixed Height Tripod Setup
Using a fixed height tripod, the setup is similar to that of the tripod setup, however the
setup is simplified by the central leg of the tripod, that is placed directly on the control
point. Provided the central leg is leveled accurately, the fixed height tripod is quick and
easy to set up, and provides an easy and accurate means of measuring the true
antenna height.
1. Set up the tripod over the control point.
2. Attach the GPS antenna to the head of the tripod
3. When using a high-gain external radio antenna, mount the radio antenna to the
radio antenna bracket, which is attached to the head of the tripod beneath the
GPS antenna. See Figure 5.4.
4. If you are using theSPSx50 Modular GPS receiver, you can hook it to the center
leg of the tripod using the tripod clip.
5. If you are using the SPSx80 Smart GPS antenna, you can mount the antenna
using the 25 cm spacer rod (supplied with the SPSx80 Base Station Accessory
kit) so that the radio antenna clears the head of the tripod.
