Iridium makes strategic investment in DDK Positioning
(24 May 2021) Iridium Communications Inc. announced that it has made a strategic investment in DDK Positioning (DDK), an Aberdeen, Scotland based provider of enhanced Global Navigation Satellite System (GNSS) accuracy solutions.
DDK uses the Iridium network to provide global precision positioning services that can augment GNSS constellations, including GPS and Galileo, to significantly enhance their accuracy for critical industrial applications. DDK is also developing similar services for other GNSS constellations, such as GLONASS and Beidou. Terms of the investment are not being disclosed.
Standard positioning accuracy through a system like GPS is typically within 10 meters; however, by using the Iridium network, DDK's enhanced GPS accuracy service brings precise positioning of five centimeters or less. This advanced level of accuracy is ideal for autonomous vehicles like UAVs, precision agriculture applications, offshore infrastructure projects such as windfarm construction, automotive applications like driverless cars, as well as a host of construction, mining, surveying and IoT use cases.
Historically, there have been limited geostationary satellite provider options for this type of service, but they suffer from line-of-sight blockage issues and coverage limitations in and around Arctic and Antarctic regions, Iridium noted.
