exactEarth announces successful launch of the ESAIL microsatellite

(3 September 2020 - exactEarth) exactEarth has announced the successful launch of the ESAIL microsatellite.

Developed under ESA’s ARTES Partnership Project for global ship tracking, the ESAIL satellite was launched September 3rd onboard the Arianespace Vega (VV16) flight, from Europe’s spaceport in Kourou, French Guiana.

The satellite will undergo commissioning testing over the next few months and then will be brought into service to provide advanced high-performance vessel detection and tracking capability as part of exactEarth’s industry-leading global constellation of more than 70 high performance automatic identification system (AIS) satellites providing real time monitoring of the global shipping fleet.

VV16 is Arianespace’s first Vega Small Spacecraft Mission Service (SSMS) rideshare flight that injected a total of 53 satellites into orbit. At approximately 52 minutes after launch, ESAIL was released into a sun-synchronous orbit with Local Time at Descending Node (LTDN) of 10:30 am at an altitude of 515 km.

ESAIL is a high-performance microsatellite, built by LuxSpace with the support of the Luxembourg Space Agency under an ESA Partnership Project with exactEarth and the support of the Canadian Space Agency. It will track ships worldwide by detecting messages that ships radio-broadcast via AIS. As part of exactEarth’s Satellite-AIS constellation, ESAIL will provide AIS data for the monitoring of maritime traffic on a global basis. It will improve fishery monitoring, fleet management, environmental protection, and security monitoring – making the seas safer.

The first contact with the ESAIL satellite was successfully made by the ESAIL project team within hours after launch. The project team, consisting of team members from exactEarth (mission operator and owner), LuxSpace (prime contractor) and the European Space Agency (project sponsor) have gained control of the satellite, which is in good health. In the coming days and weeks, the satellite will undergo commissioning and in-orbit testing prior to being put into service as part of exactEarth’s Satellite-AIS constellation. The ESAIL satellite is designed for a mission life of approximately four years.

“We are very excited to add this advanced technology satellite to the exactEarth constellation,” said Peter Mabson exactEarth CEO. “ESAIL incorporates advanced antenna and receiver designs which, together with exactEarth’s advanced decollision processing technology is expected to set a new standard for Satellite-AIS vessel detection. I would like to thank ESA, the CSA and the Luxspace-led European satellite manufacturing team for helping to achieve this important milestone. Onwards and upwards!”

About exactEarth

exactEarth is a leading provider of global maritime vessel data for ship tracking and maritime situational awareness solutions. Since its formation in 2009, exactEarth has pioneered a powerful new method of maritime surveillance called Satellite AIS and has delivered to its clients a view of maritime behaviours across all regions of the world's oceans unrestricted by terrestrial limitations. exactEarth’s second-generation constellation, exactViewTM RT, securely relays satellite-detected AIS vessel signals from any location on the earth’s surface to the ground in seconds – thus enabling global real-time vessel tracking. This unique capability consists of 58 advanced satellite payloads designed and built by L3Harris Technologies, Inc. under agreement with exactEarth and that are hosted onboard the Iridium NEXT constellation of satellites.
