June 2012, I wrote a post about the future constellation of communications satellites Iridium NEXT. While intended for operational use in 2017, the calendar was shifted a few months. Actually, the launch of the first ten satellites by the private company SpaceX, originally planned on 12 September 2016, was postponed for a few months by the explosion on September 1, a Falcon rocket 9 rocket explosion during the fuel filling on its launch pad before a shot of engine test.

Ultrasonic anemometers-weathervanes for yachting came up just over 15 years. Among the best known include those of the US Airmar and French LCJ Sensors. Featuring sophisticated electronics, these sensors without moving mechanical parts have the advantage of being more robust than conventional sensors, and provide more accurate data. They can also integrate other sensors as barometer, gyroscope, electronic compasses and even GPS.
The first ultrasonic sensors were fitted with a cable for power and data transfer. The manufacturer LCJ Sensors, building on the success of its CV3F sensor marketed since 2001, designed the range CV7SF, wireless models whose data is transmitted over a radio frequency to a receiver which converts them into NMEA (0183 or 2000). Power is supplied by solar cells on the sensor cap, and different output connection interfaces are proposed according to the models.
A new player, Spanish Calypso Instruments, just design a wireless sensor of a new concept, the Calypso Ultrasonic Portable, whose characteristic is to be featured with a Bluetooth Low Energy Transmission Protocol (Bluetooth 4.1), which offers many advantages.

comments Off Test on the Nomad – stand-alone AIS transceiver by Digital Yacht
I introduced last may the Nomad, a portable AIS transceiver designed by Digital Yacht. I had to wait until the end of the summer to have the opportunity to test in real situation this device that had been entrusted to me by the manufacturer. I can already say that I was conquered.
I conducted the test in two phases. The first in my home port of St-Vaast-La-Hougue in my own boat, to the pontoon, and at low tide, the port doors closed - the context is important - for the commissioning of the reception only. The second at sea, in Roussillon, with setting the transmission service. Read more →
