CHAPTER 2 SITING AND SETUP

SITING CONSIDERATIONS

2-1

The following siting considerations must be addressed:

2-1.1

Compass Accuracy

The WEATHERPAK

for automatic alignment to True North. If placed

laterally near a large mass of steel or other magnetic

material, an erroneous compass reading may result.

(The top of a van is OK, but next to it is not an ideal

location). Try to place the WEATHERPAK

30 meters laterally from large vans, busses, cranes,

etc.

Proper Wind Measurement

2-1.2

Select a site that is as unobstructed as possible. Structures, trees, terrain, etc. will disrupt the wind flow for a

considerable distance. For example, if the WEATHERPAK

wind is coming from the South, an erroneous wind data reading will result.

Radio Transmission

2-1.3

Deploy the WEATHERPAK

a range of 5 to 7 miles

hills.

2-1.4

GPS Operation

There is a GPS receiver inside the MTR Receiver/Display box and a GPS receiver inside the WEATHERPAK

MTR. These GPS receivers work together and provide data to the SmartDetect™ firmware, which in turn

furnishes direction and distance information for additional WEATHERPAK

MTR receiver will also accept data from Coastal Environmental Systems' WEATHERPAK

since only the MTR has a GPS, location information for the others is not available).

The GPS in the Receiver/Display must be connected to an external GPS antenna. The receiver will

automatically begin to search for and track GPS satellite signals at power-up. The antenna must have good

exposure to the sky.

The performance of a GPS receiver at power-up is determined largely by the availability and accuracy of the

satellite ephemeris data and the availability of a GPS system almanac. When the WEATHERPAK

up, the GPS searches for satellites from a cold start (no almanac). The GPS will begin to compute position

solutions within the first two minutes. The WEATHERPAK

upon arrival at the incident scene.

2 This distance assumes ideal conditions. Reception range will vary depending on radio signal path.
