Space X has launched the Paz mission with two experimental satellites Tintin A (Microsat-2a) and Tintin B (Microsat-2b) from the Space Launch Complex 4E at California's Vandenberg Air Force Base.
Space X has completed the launch of its mission using a recycled Falcon 9 rocket.
These two satellites, if successful will pave the way for Star link, a constellation of satellites that would provide a cheap, high speed, global Internet connection.
Star link will have 12,000 small satellites in two layers — low earth orbit (LEO) and very low earth orbit (VLEO).
The LEO constellation will provide high-speed broadband services around the world; the VLEO constellation will enhance capacity.
The UN Broadband Commission for Sustainable Development estimated in 2016 that 57% of the world’s population was offline.
Paz mission is mainly about the Spanish radar imaging satellite with applications such as border control, intelligence, military operations, environmental monitoring.
Satellites in LEO constellation will operate in the frequency bands of Ku, Ka and V band.
Satellites in VLEO constellation will operate in the frequency bands of V band.
LEO located in the altitude of 1110-1325 km above the earth.
VLEO located in the altitude of 335-346 km above the earth.
