Volunteering for  SAR

NRRL_samb_150_copyThe most active group at LA3T is "Sambandstjenesten" (Emergency Communication Service), the members are a part of the volunteer emergency service in the Tromsø-area. "Sambandstjenesten" contributes with VHF/UHF/HF communication for areas without mobile phone coverage or when the GSM service is unavailable.

Another important service we deliver is APRS tracking, this aid has become very popular both within the other volunteer SAR-organisations, Røde Kors Hjelpekorps (Red Cross Search and Rescue Corps), Norsk Folkehjelp (Norwegian People’s Aid Health and Rescue Service) and others and within the professional organisations as Sivilforsvaret (The Norwegian Civil Defence) and the Police.


Polaric Tracker and  ServerPolaricTracker_1

Members of LA3T have developed a tracker solution  based on both hardware and software components to deliver a "professional" and stable tracking service to our partners in the SAR services.

The Polaric Tracker is a handheld, battery operated complete APRS tracker for radio amateurs and SAR teams. The Polaric Tracker has a batterytime of approx. 30 hours and a fast charge of about 30 minutes. The unit operates on 144,800 MHz and is waterproof corresponding to IP54.


The Polaric Server is a "stand-alone" or Internet service map presentation system based on a APRS receiver and presentation service on a Linux platform. Check http://aprs.la3t.no for the Internet service based on Polaric Server.

For SAR use LA3T have a "grabbag" consisting of a VHF radio, antenna, battery and a PC configured with Polaric Server.
