This user guide came out of a meeting that took place between SAR and the Communications Center. A thank you to Steve Allen, Duffy Bruegmann and Jon Mercer who represented SAR.

This document is not meant as policy of any kind, it is merely an explanation of how the process works. Dpty. Kathy Decker will be working with the Communication Center to develop a "policy" for these inquiries. Once we have policy in place we will begin to train using that policy.

  1. Identify phase I or Phase II. Phase I is based off of a tower; Phase II is based off of the location of the phone. A Phone with GPS capability in a clear open sky will allow for triangulation and a phone with a clear strong signal will allow for possible triangulation from multiple towers.
  2. Have call receiver hit the RTX button at least two times to give the system an opportunity to go from Phase 1 to Phase 2. If the call is weak or scratchy this would allow for an attempt at a clear, strong signal the second time around, which may allow the system to upgrade to a phase 2.
  3. If a tower is busy the first time the signal will search out the next available tower, which may be miles away, in another county or state.
  4. The data will be coming into the Communication Center as Decimal Degrees, WGS 84 (map datum).
  5. The Communications Center may go through the phone company to ping the phone, if the phone is turned on. The phone company may be able to get location information based upon that ping process.
  6. The subject has to call 911 in order for the Communications Center to get location information through the system.
  7. The Communications Center may call the phone company directly, state an emergency
