Ncube-2, a Norwegian CubeSat (10 cm (3.9 in) cube). A CubeSat is a class of small satellite with a form factor of 10 cm (3.9 in) cubes. [1] CubeSats have a mass of no more than 2 kg (4.4 lb) per unit, [2] and often use commercial off-the-shelf (COTS) components for their electronics and structure.
A satellite constellation is a group of artificial satellites working together as a system. Unlike a single satellite, a constellation can provide permanent global or near-global coverage , such that at any time everywhere on Earth at least one satellite is visible.
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.
For example, a 6U CubeSat standard has been proposed to enable a satellite constellation of thirty five 8 kg (18 lb) Earth-imaging satellites to replace a constellation of five 156 kg (344 lb) RapidEye Earth-imaging satellites, at the same mission cost, with significantly increased revisit times: every area of the globe can be imaged every 3.5 ...
Satellogic began launching their Aleph-1 constellation of ÑuSat satellites in May 2016. [12] On 19 December 2019, Satellogic announced they have received US$50 million in funding in the latest funding round. [3] In January 2022 the company went public with a special-purpose acquisition company (CF Acquisition Corp. V) merger. In connection ...
SBUDNIC was launched to test Arduino Nano and other commercial off-the-shelf technology in space, using a simple, open-source design. [2]An ambitious project is the QB50, an international network of 50 CubeSats for multi-point by different universities and other teams, in-situ measurements in the lower thermosphere (90–350 km) and re-entry research.
TROPICS (Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats) [5] is a NASA constellation of four identical 3U CubeSats designed to perform detailed and frequent studies of tropical cyclones.
Edison Demonstration of Smallsat Networks (EDSN) was a failed (launch failure) CubeSat constellation by NASA Ames, developed as a technology demonstration of satellite networking. The constellation would have consisted of 8 identical satellites. The satellites followed the CubeSat specifications for a 1.5U CubeSat.
