KSF2: Patrol


Creating a constellation that provides critical coverage for monitoring global events and key locations of interest.

Patrol Mission (KSF2) satellites launched on the 1st of April 2022 from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida onboard the SpaceX Falcon 9 Transporter-4 mission.

Patrol Mission

Launching into a 500-600km Sun Synchronous orbit, the Patrol Mission satellites expand Kleos’ data collection capability by up to an additional 119 million km² per day. This mission also enables Kleos to increase its average daily revisit rate over a 15-degree latitude area of interest to around five times a day.

Kleos Patrol mission remanifested to fly on D-Orbit’s ION Satellite Carrier for next orbital transportation mission (published by D-Orbit): 08/03/22

The space logistics and orbital transportation company signed a contract with US launch provider Spaceflight Inc. to deliver the Kleos Patrol Mission (KSF2) satellites into orbit aboard the next ION Satellite Carrier mission, scheduled for April 2022. 

Kleos’ Patrol Mission Satellites Ready and Shipped to Launch Site: 09/12/21

Kleos confirms its Patrol Mission (KSF2) satellites are on track to launch onboard the Transporter-3 SpaceX mission in January 2022, successfully passing the final technical milestone with satellite builder Innovative Solutions In Space (ISISPACE).  

Kleos commits to build and launch fourth satellite cluster: 19/10/2021

Kleos has signed new contracts with satellite builder Innovative Solutions in Space B.V. (ISISPACE) and global launch services provider Spaceflight Inc to build and manage the launch its fourth satellite cluster of four satellites, the Observer Mission (KSF3) mid-2022.

Behind the Scenes: Testing the Polar Vigilance Mission Satellites before launch

Discover the different testing phases the Polar Vigilance Mission Satellites went through before #launch!

Kleos’ 2nd cluster of satellites, the Polar Vigilance Mission (KSF1), are being launched into a 525km Sun Synchronous orbit to enhance our global data collection capability.

Satellites are on route to Cape Canaveral: 01/06/21

Our four Polar Vigilance Mission satellites (KSF1) are now enroute to Cape Canaveral Space Force Station. Under a rideshare contract with Spaceflight Inc., the satellites will lift-off aboard the Spaceflight SXRS-5 / SpaceX Transporter-2 mission 

“We look forward to them entering service in our growing constellation – more satellites, means more data for our customers, increasing their insight into human activity in key areas of interest”

Kleos’ Polar Vigilance satellites pass Integration Readiness Review

Kleos Space confirms development of its second satellite cluster, the Polar Vigilance Mission (KSF1), is on track for a mid-2021 SpaceX launch after successfully completing Integration Readiness Review, and the satellites start the build process with satellite builder ISISPACE.

The four Polar Vigilance nanosatellites are in the assembly and testing phase in preparation for final acceptance. Kleos’ satellites will then be delivered to the launch site for integration into the SpaceX Falcon 9 launch vehicle.

Kleos completes key satellite development milestone for mid-year SpaceX launch

Kleos confirms its second satellite cluster, the Polar Vigilance Mission (KSF1), has successfully completed a hardware critical design review milestone for a launch mid-year onboard a SpaceX Falcon 9. Conducted, in the Netherlands, by satellite developer ISISPACE, passing the milestone ensures that Kleos’ Polar Vigilance Mission satellites can enter the assembly and verification phase – an exciting stage leads to final integration, testing and delivery of the satellites for launch.

Launch Schedule

7th November 2020

The Kleos Scouting Mission comprising four satellites (KSM1a, KSM1b, KSM1c, KSM1d) has launched on Indian Space Research Organisation (ISRO) PSLV C49 from Sriharikota Range in India (SHAR) into a 37 degree inclined orbit.

June 2021

The Kleos Polar Vigilance Mission comprising four satellites (KSF1a, KSF1b, KSF1c, KSF1d) will launch on the SpaceX Falcon 9 into a 525km Sun Synchronous Orbit.

April 2022

Launch and satellite contracts placed for Polar Patrol Mission.

Our Mission:

The development of our KSF1 satellites progressed at an incredible pace. We are leveraging the experience of our satellite builder, Netherlands-based ISISPACE, to develop and deliver quickly as well as improve our hardware and software capability. We are rapidly building our constellation in 2021 with two satellite launches planned this year. Each satellite cluster increases the volume and value of our radio frequency geolocation data, enabling tiered subscription licences for governments and commercial entities.
