“…It aims to investigate the physical processes responsible for the formation of the ionospheric storm‐enhanced density (SED) bulge and the relationship between penetration electric fields and SED formation. To test the possibility to use CubeSats as data relays in order to increase the time available for satellite to ground station communications and the throughput capacity is the aim of CommCube 1 and CommCube 2 missions developed at the Massachusetts Institute of Technology . The QuakeSat mission objective is to detect, record, and send extremely low‐frequency (ELF) magnetic signal data, which may lead to the prediction of earthquakes, to a ground station.…”

Summary The space environment is still challenging but is becoming more and more attractive for an increasing number of entities. In the second half of the 20th century, a huge amount of funds was required to build satellites and gain access to space. Nowadays, it is no longer so. The advancement of technologies allows producing very small hardware components able to survive the strict conditions of the outer space. Consequently, small satellites can be designed for a wide set of missions keeping low design times, production costs, and deployment costs. One widely used type of small satellite is the CubeSat, whose different aspects are surveyed in the following: mission goals, hardware subsystems and components, possible network topologies, channel models, and suitable communication protocols. We also show some future challenges related to the employment of CubeSat networks.

“…Transmitter: A generic CubeSat transmitter is considered. The transmitter output power is assumed to be 1 W which is consistent with the current transceivers' capabilities for CubeSat in S-Band [1] [3]. The antenna gain is estimated to 0 dB with 2 dB of pointing loss and 1 dB of transmitter loss (conservative estimates).…”

Interplanetary Cubesats would enable low-cost missions for high-quality scientific and exploration programs. In particular cubeSats in formation have been proposed to operate in the vicinity of the Lunar Lagrangian L1 to collect lunar scientific data and to perform surface observation. In this paper we present a low complexity CDMA system for CubeSats (M small spacecraft) for communications between the Lunar L1 and Earth station. It is well known that the complexity of a CDMA transmitter is much lower than the complexity of the CDMA receiver. Moreover, the complexity of a channel encoder is always much lower than the complexity of the channel decoder. So for downlink communications it makes sense to use encoders for modern codes such as Turbo and LDPC followed by a spread spectrum transmitter for CDMA systems for CubeSats. Here we used an LDPC coded CDMA with BPSK modulation with rectangular and half-sine pulse shaping. Except for the PN generator seed numbers, the communication structure of all CubeSats would be identical and operating at one single RF frequency. For the uplink we may choose an uncoded CDMA system since the uplink transmit power is expected to be high enough to support the use of uncoded CDMA system. In addition since there would be no multipath for the uplink (broadcast channel) the use of orthogonal spreading codes such as Walsh codes is appropriate. The choice of orthogonal codes would reduce the multiuser interference. However due to some limitation (bandwidth, data rates, and M) we may be forced to use nonorthogonal PN codes. In addition, one of the spreading codes will not carry any data, which acts as an unmodulated pilot to reduce the complexity of synchronization. The proposed uncoded CDMA yields receivers for CubeSats that have low complexity implementation. Each component of CubeSats could easily extract its own received data with almost no interference from other users in case of orthogonal spreading codes. For the downlink, depending on the available bandwidth, and the data rates, a large processing gain could be obtained if the N is not large. Thus the multiuser interference degradation due to the other CubeSats could be made small at the Earth station. If N is large, and the bandwidth and data rates do not allow large processing gains then the multiuser interference could be high. In such cases we could use a simple parallel interference cancellation method with two stages that dramatically improves the system performance for the downlink. In this paper we accurately analyzed and simulated the proposed CDMA system for a concept Constellation of 20 CubeSats (M=20). All system simulations are done using Simulink platform.

Abstract-Cubesat constellations may become the next generation of communication backbone architecture to provide future worldwide communication services. In this paper, we investigate the feasibility of deploying Cubesat constellations with inter-satellite links (ISL) for the delivery of global continuous communication. Cubesat constellation designs for various mission scenarios are proposed and verified using a simulation toolkit commonly used by space engineers.Index Terms-Cubesat, inter-satellite links, binary phase shift keying, code shift keying, low earth orbit, pilot symbol, sensor, Mary frequency shift keying, M-ary phase shift keying, quadrature phase shift keying, Systems Tool Kit, unmanned aerial vehicle.
