(Kleos or Company), a space- powered Radio Frequency  Reconnaissance data-as-a-service (DaaS) company, provides as Annexure A, the Geolocation System  technical paper describing its recent successful technical milestones to be presented publicly at the  GEOINT21 symposium exhibition on the 6th October 2021. 

Kleos’ CTO Vincent Furia explained, “In order to present our technical capability at the GEOINT21  symposium, we are releasing a detailed technical paper explaining how the RF data captured by Kleos’  constellation of satellite clusters is processed into geolocation information for our customers. 

We also showcase a recent case study completed over the Republic of Cabo Verde, which demonstrates great and better than expected results of the geolocation system performance, using a data capture  coming from the Scouting Mission (KSM1) cluster of 4 satellites. 

Kleos continues to develop and deploy a constellation of satellite clusters, delivering revisit rates over  key areas of interest with increasing operational value to the user. With every new cluster added, further  data is collected, creating a higher value data set accessible by the various government and commercial  users.” 

Kleos’ Intelligence, Surveillance, and Reconnaissance (ISR) capability uses nano-satellite clusters  operating in low earth orbit to collect data to geolocate radio frequency (RF) emissions. The capability  seeks to geolocate emissions to detect illegal activity, including piracy, drug and people smuggling, border  security challenges and illegal fishing. Its global activity-based data is sold as-a-service to governments  and commercial entities, complementing existing commercial datasets.

About Kleos Space S.A. 

Kleos is a space-enabled radio frequency reconnaissance data-as-a-service company with operations in  Luxembourg, the US and UK. Kleos locates radio transmissions in key areas of interest around the globe,  efficiently uncovering data points to expose human activity on land and sea. Using clusters of four  satellites, proprietary radio frequency data (RF Data) is collected, transmitted to the ground, processed,  and delivered to customers worldwide. Customers, including analytics and intelligence entities, will 

license data on a subscription basis (Data-as-a-Service aka DaaS), for government and commercial use  cases – aiding better and faster decision making. Kleos’ first satellite cluster, the Kleos Scouting Mission  (KSM), successfully launched in November 2020 is performing as a test and technology demonstration  whilst collecting data. The company’s second satellite cluster, the Polar Vigilance Mission, successfully  launched in June 2021 and its Polar Patrol Mission is scheduled to launch on the next SpaceX Transporter  mission. These satellite clusters form the foundation of a global high-capacity constellation of up to 20  satellite clusters, which will deliver high value global observation.
