Kleos space S.A. , a space-powered Radio Frequency Reconnaissance data-as-a-service (DaaS) company, has changed launch provider for its Scouting Mission

satellites which will now launch into a 37-degree inclination. Following the recent postponement of the launch of Kleos' Scouting Mission satellites, the Company investigated other available launch options with launch and mission management provider Spaceflight Inc. that would meet immediate market demand and potentially increase the value of the data collected.

The 37-degree orbital inclination gives the Kleos' Scouting Mission cluster of four satellites improved data collection by a factor of between 2 and 4.5 times over crucial shipping target regions such as The Strait of Hormuz, South China Sea, Australian Coast, Southern US Coast and both East and Western African Coast when compared with the originally planned Sun Synchronous Orbit (SSO).

Since the original choice of SSO was made over a year ago, the threat level in the equatorial regions has increased and Kleos has made significant progress in engaging the market and securing defence and security customers who have an interest in these regions, where increased coverage provides better data and improved mission critical information for customers.

Keeping within the Q4 2019 launch window, the Company will now launch under a rideshare contract with Spaceflight Inc. on the PSLV into a 37-degree inclination orbit. The Polar Satellite Launch Vehicle (PSLV) is a highly reliable expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO).

The scouting satellites remain ready to fly. The Kleos team has analysed and confirmed compatibility with the satellites flying in a 37-degree inclination. Unlike most earth observation missions which fly in an SSO to allow for the sun to illuminate their targets for imagery, Kleos technology means its satellites can observe RF transmissions at any time of day because they are not dependant on sunlight.

The original SSO is nearly a polar orbit that maintains its relationship with the sun which is useful for power generation and for missions that rely on illumination of the target. SSO gave full global coverage, with good revisit times of the polar areas. PSLV C49 is in a 37-degree inclination, which is where the satellites orbit traverses between 37 North latitude and 37 South latitude. The coverage is broadly bounded by Lisbon in the North and Melbourne in the South delivering far improved revisit times around the equatorial regions at the expense of coverage in the far North and South.

The following graphics firstly show the potential of data collection by the Scouting satellites in their new orbit the from the key regions of interest with excellent revisit rates when compared with SSO, and secondly the Worlds maritime illegal activity/piracy hotspots highlighted in The State of Maritime Piracy 2018 report from One Earth Future.

The multi-satellite Scouting Mission system will form the foundation of a constellation that delivers a global picture of hidden maritime activity, enhancing the intelligence capability of government and commercial entities when AIS (Automatic Identification System) is defeated, imagery is unclear, or targets are out of patrol range. The first scouting mission is made up of 4x nano-satellites built by GomSpace in Denmark, each the size of a shoebox.
