In the Type column, the number corresponds to the (approximate) length of the CubeSat in decimetres. Width and depth are normally ten centimetres, or one decimetre. A 1U CubeSat measures approximately 1 × 1 × 1 decimetres, while a 6U CubeSat is six times the size, approximately 1 × 2 × 3 decimetres. [45]
The number of joined units classifies the size of CubeSats and according to the CubeSat Design Specification are scalable along only one axis to fit the forms of 0.5U, 1U, 1.5U, 2U, or 3U. All the standard sizes of CubeSat have been built and launched, and represent the form factors for nearly all launched CubeSats as of 2015. [ 30 ]
Flock-1 is a CubeSat satellite constellation launched on 9 January 2014.The satellite is built in a CubeSat bus, and each constellation consists of 28 satellites. All instruments are powered by solar cells mounted on the spacecraft body, along with triple-folded wings, providing approximately 20 watts at maximal power.
First pair of the 28 Planet Labs satellites launched from the ISS via the NanoRacks CubeSat Deployer (2014). Planet Labs was founded in 2010 as Cosmogia by former NASA scientists Chris Boshuizen, Will Marshall, and Robbie Schingler, who teamed up with John Kuolt in 2011 during his studies at Oxford University with a thesis to leverage the processing power of mobile phones to power the avionics ...
The Astra Rocket 3.3 vehicle (serial number LV0010) carrying two satellites for the TROPICS-1 mission failed to reach orbit and the satellites were lost. [ 15 ] [ 16 ] Following the retirement of Rocket 3.3 on 4 August 2022, it was reported that NASA intended to wait for Astra's Rocket 4 to be developed for the launch of the remaining four ...
Total number of CubeSats: 32. Planet Labs: Doves, Flock 1A (28) Purpose: These 28 3U CubeSats are working to build an Earth-observation constellation based solely on CubeSats. The CubeSats contain batteries that provide power to the various systems in each Dove. Each satellite has an optical telescope for acquiring high-resolution images of earth.
SpaceBEE is a constellation of picosatellites, predominantly in the CubeSat 0.25U form factor, intended to reach a quantity of 150. [25] SpaceBEE test models 5 to 9 were larger to assuage concerns about radar tracking. Swarm's website lists the satellites' mass at 400 g and size at 110 × 110 × 28 mm.
The company currently operates a fleet of more than 110 CubeSats, the second largest commercial constellation by number of satellites, [6] and the largest by number of sensors. The satellites are integrally designed and built in-house. It has launched more than 140 satellites to orbit since its creation. [7]
