This allows all the Sprites on a particular mission to share the same allocated frequency, simplifying licensing and eliminating the need for clock synchronization that would otherwise be required for the Sprites to alternate transmitting on the same frequency.

• PhoneSat-2.5, a technology 1U CubeSat of NASA/ARC to continue technology demonstrations of the PhoneSat CubeSat series. Therefore, the Sprites can operate only in sunlight and will be completely unpowered in the eclipse phase of the orbit. The Sprites are a tiny spacecraft that includes power, sensor, and communication systems on a printed circuit board measuring 3.5 by 3.5 cm with a thickness of 2.5 mm and a mass of about 5 grams. A lack of closed-loop attitude control means a low-gain antenna with an omnidirectional gain pattern is required. The antenna is made of nitinol, a nickel-titanium alloy commonly referred to as “shape-memory alloy” or “memory metal,” which can be deformed to a tremendous degree and still return to its original shape. Over the next three to four days, the attitude control system in the bus will be used to point KickSat’s minor axis of inertia (long axis) at the sun, and then spin the spacecraft up to 10-15 rpm about the sun vector, ensuring attitude stability during the deployment sequence. However, the automatic timer that was to release the satellites was reset by the onboard “watchdog” microcontroller on 30 April 2014, probably due to a high dose of radiation (it appears the reset happened some time in the morning of April 30). A launch on Cygnus CRS-5 was then planned, but issues with the experimental license from the FCC delayed it to a later launch. 10). A 1U avionics bus will provide power, communications, and command and data handling functions. [8][9][10] It may serve as a test bed for further communication and attitude control experiments during that time. Upon their return to Earth, they were still functional. On April 30, 2014 the microcontroller managing the master clock was found to have reset due to a technical problem, an effect of space radiation. Upon being exposed to sunlight, the Sprites will immediately be powered on and will begin taking sensor measurements and transmitting telemetry. and also as "cracker size". [11][12][13][14], In its minimal configuration, each Sprite femtosatellite will be designed to send a very short message (a few bytes long) to a network of ground stations. Additionally, due to licensing constraints, the Sprites must efficiently share limited RF bandwidth. Once a stable sun-pointing attitude has been established, all systems have been checked out, and KickSat is in view of a ground station, a signal from the ground will trigger a nichrome burn wire to unlock the deployer. The nitinol wire antennas on the Sprites are coiled in such a way that they act as springs, pushing the Sprites out of their slots.

The hardware designs, code, and documentation for all of these systems are being released under open-source licenses where possible. While there are no strict pointing requirements, the goal of this spin stabilization is to keep the Sprites’ solar panels pointed largely at the sun for the short mission lifetime and to minimize nutation, which would otherwise introduce attitude-dependent fluctuations in power. Eventually it was launched on the ELaNa-16 mission on board of the Cygnus CRS-10 cargo vehicle and was deployed on 13 February 2019 from the spacecrafts external deployer after departing from the ISS.

The launch site was Cape Canaveral, FL. After being released from the P-POD, KickSat will perform a de-tumble maneuver and establish communication with Cornell’s ground station.
