    Seen & Heard: smartphone drop, yacht rescue

    “Seen & Heard” is a monthly feature of GPS World magazine, traveling the world to capture interesting and unusual news stories involving the GNSS/PNT industry.

    Lost and found

    Taking video from an airplane window 300 feet up carries its share of risks, discovered Brazilian documentary filmmaker Ernesto Galiotto. The bad news: A strong wind snatched his iPhone 6 from his hand. The good news: GPS enabled him to recover the phone, which suffered only a minor crack in its protective cover. The best news: The phone captured the entire 15-second drop on video. The incident happened over Peró beach 75 miles east of Rio de Janeiro, reported Brazilian news outlet G1.

    Finding particular trees in the forest

    Locating and documenting a single tree in a forest planting can be difficult. Technicians at Land Life, an Amsterdam-based land restoration company, have switched from using QR codes and readers for tree identification to GNSS. By replacing the QR codes with accurate GNSS positioning, Land Life produced a four-fold increase in monitoring productivity. The company measures sapling height and health and combines that data with tree species, location, soils and environmental conditions to support planning and care. Field teams now use a Trimble R1 GNSS receiver to stream positioning data via Bluetooth to their smartphones.

    Answering an SOS

    Yacht skipper Kevin Escoffier faced disaster during the Vendée Globe solo round-the-world sailing race. His yacht was pounded apart in raging seas 840 nautical miles southwest of Cape Town, South Africa. Once his raft hit the water, its rescue beacon activated. Through the Cospas-Sarsat service, the signal moved from Galileo satellites to ground stations in Toulouse, France, to Canberra, Australia, then to race directors, who sent the closest competitor to assist.

    No stopping required

    India will be free of toll booths in two years, said Nitin Gadkar, the country’s transportation minister. According to the Times of India, the government will roll out GPS-based tolling across its national highway sytem. Tolls will be deducted directly from drivers’ bank accounts based on distance traveled. While commercial vehicles registered after January 2019 have tracking systems, the government has yet to outline plans to install GPS receivers in older private vehicles.

  • Spectra Geospatial GNSS receiver chosen for around-the-world yacht race

    The Spectra Geospatial SP90m GNSS receiver will guide the racing yacht Maître CoQ for the 2020 Vendée Globe, single-handed, non-stop around-the-world yacht race. The Vendée Globe is an extreme endurance test for both sailor and boat and widely considered the ultimate challenge in ocean racing. The race starts Nov. 8 and is expected to finish in late January or early February.

    The SP90m will provide the skipper of the Maître CoQ, Yannick Bestaven, with precise position and boat heading information. The SP90m information is integrated to a separate attitude information source, and the entire package of the position, heading and attitude is sent to the boat’s autopilot.

    Bestaven, responding to the changing sea and wind conditions, strategically adjusts the autopilot to keep the boat moving at top speed to the desired destination as he changes and trims sails and trims foils to achieve maximum sailing efficiency.

    The Maître CoQ is an advanced design mono-hull foiling sailing yacht in the category of IMOCA (International Monohull Offshore Class Association) which have a fixed length of 18.28 meters (60 feet), Antoine Connan, head of engineering for the Maître CoQ racing team, selected the SP90m.

    The hostile environment and requirements for precise position information at sea far from land made the selection of the SP90m an important technical choice. It always delivers an accurate position and precise heading with no GNSS corrections.

    Commenting on the performance of the SP90m in the recent July 2020 2,800-mile qualifying race, the Vendée- Arctique-Les Sables D’Olonne, Connan reports, “We are already very happy with its installation on board.”

    The SP90m is a rugged design for marine environments. With 480-channel tracking and dual GNSS antenna inputs, the SP90m is an integrated onboard rover receiver offering minimal size and low power consumption.

    When the Maître CoQ technical team, based in La Rochelle, decided they needed to upgrade the boat’s navigation system, they contacted Cadden, a specialist in supplying advanced electronic precision measurement sensors. In addition to the requirement for delivering fast, precise position and heading data, the new sensor had to be lightweight, small, require little power, be easy to integrate, and flawlessly withstand a hostile saltwater environment. Cadden’s analysis concluded the Spectra Geospatial SP90m fit the spec perfectly.

    “We are thrilled that the Maître CoQ racing team selected the Spectra Geospatial SP90m,” said Olivier Casabianca, vice president Spectra Geospatial. “It’s one more confirmation that Spectra Geospatial provides truly the highest quality rugged and precise GNSS receivers.“

    About the Vendée Globe 2020. Held every four years, the Vendée Globe is a single-handed (solo) non-stop yacht race around the world without assistance. It starts and finishes in Les Sables-d’Olonne in the Département of Vendée in France. The course is a circumnavigation from Les Sables- d’Olonne, that heads south in the Atlantic Ocean to the Cape of Good Hope, then east in the Southern Ocean clockwise around Antarctica, keeping Australia’s Cape Leeuwin and South America’s Cape Horn to port (to the left); and then back north in the Atlantic returning to finish in Les Sables-d’Olonne.
