Dear Customers and Partners, season's greetings from Aeromarine SRT Team!

Season Greetings

Ready for 2020?

We are! But first let’s make a short resume and thank 2019.

In this year:

  1. The GMDSS Multi Tester MRTS-7M became our top sales device (yuhoo!)
  2. We launched a new product – SART Tester STU-1 (that had great demand by the way and the widescale production has been already planned for the next year)
  3. We released Multi-Compatible Software with cloud storage (one for all testers, you remember)

Galileo Innovates Search and Rescue

Category: General

In 2020 the Galileo Navigation Satellite System will present Return Link Service.

With it, anyone who got into emergency situation and uses a Cospas-Sarsat receiver will be assured that his SOS signal is received and help is surely coming.

Galileo Navigation Satellite System Helicopter

The development of international search and rescue service started with the launching of the Cospas-Sarsat global distress satellite network in 1981, continued in the 2000s when in the 406MHz search and rescue beacons the GPS receivers were installed and the location identification with the accuracy within 100 meters became possible.

Thus such devices as AIS SARTs, GPS EPIRBs and PLBs, AIS MOBs appeared. The progress moves on and now we are approaching to the new stage of search and rescue service development.

ELT Testers at Paris Air Show 2019

Category: General

As you know, one of Aeromarine SRT directions is manufacturing equipment for ELT testing. We always do our best to keep up with the times and it helps us to make our devices progressive and reliable.

So to learn more about achievements and innovations in the field of avionic testing, our team got going to the International Paris Air Show 2019 that took place in Le Bourget in the beginning of the summer.

EPIRBs

We got opportunity to study the features, found out novelties in the sphere of avionic technologies and of course communicated with other manufacturers for experience exchanging.

406MHz ELT Tester

406MHz ELT Tester

406 MHz / 243 MHz / 121.5 MHz ELT TESTER (ELTT-124 Test set) is designed to check the avionics emergency locator transmitters (ELT) operating via COSPAS-SARSAT system. Complies with USA (FAA Part 91.207), Canada (CAR 571 Appendix G), Europe (CAA/EuroCAE) requirements.

ELT Tester Mini Wi-Fi

ELT Tester Mini Wi-Fi

ELT Tester Mini Wi-Fi is third generation device designed to check the avionics emergency locator transmitters (ELT) operating via COSPAS-SARSAT system. Tester is operating with any mobile phone or desktop PC by means of Wi-Fi connection.

GADSS Tester GT-1

GADSS Tester GT-1

The GT-1 is a compact, lightweight unit for testing of 406 MHz COSPAS/SARSAT ELT (ELT-DT) Emergency Beacons, HF/VHF/UHF (AM/FM) Communications avionic Systems, 121.5/243 MHz Short Range Emergency Beacons and AIS transmitters.

Limit your 406 MHz Testing time

FAA regulations, Title 14 Code of Federal Regulations Section 91.207(d)(4), requires that an aircraft emergency locator transmitter (ELT) be tested annually for “the presence of a sufficient signal radiated from its antenna.” The Aeronautical Information Manual (AIM) in Chapter 6, Section 6-2-5, discusses ELTs, their use, and how to test them. To paraphrase a statement from a movie about a failed trip to the Moon, “Folks, we have a problem.” The FAA requires an ELT radiated test, but if the test is not done properly, the Federal Communication Commission (FCC) might take enforcement action against the person doing a 406 MHz ELT test.

Here is the problem. When the FAA test requirements were written, the basic ELT was an analog 121.5 MHz unit transmitting in the aeronautical frequency band. If the ELT being tested could not be isolated within an approved radio frequency shielded room or container, which keeps the signal from going beyond the room or container, a radiated test could be done within the first five minutes after the hour. The test requirements listed the number of recommended sweeps of the signal to minimize the risk of anyone thinking the test signal was an actual distress alert. The person doing the test would quickly activate the ELT, listen for its distinctive sound on a nearby aeronautical band aircraft radio or handheld transceiver and then turn off the ELT.

Distress Beacon Testing

Cospas-Sarsat 406 MHz distress beacons should only be activated when a ship, aircraft or person is in distress that is in grave and imminent danger and requiring immediate assistance. In between the manufacturers’ recommended maintenance and battery replacement cycles, the beacon can be tested by the owner using the self-test capability to ensure the continued functionality of the beacon.

There is normally no need for the beacon to be tested in an operational mode by a beacon owner.

The information provided in the following sections provides guidance on beacon testing and the procedures required in the unlikely and unusual event that an operational test of a beacon is required. The Maritime Safety Authority (MSA) does not grant approval for beacon operational tests unless the procedures outlined below have been adhered to.
