DRAGON - 8U Nanosatellite Orbital Deployer
DRAGON - 8U Nanosatellite Orbital Deployer Marcin Dobrowolski*, Jerzy Grygorczuk*Â ÃB_*, Marta Tokarz* and Maciej Borys* Abstract The Space Research Centre of the Polish Academy of Sciences (SRC PAS) together with Astronika company have developed an Orbital Deployer called DRAGON for ejection of the Polish scientific nanosatellite BRITE-PL Heweliusz (Fig. 1). The device has three unique mechanisms including an adopted and scaled lock and release mechanism from the ESA Rosetta mission MUPUS instrument. This paper discusses major design restrictions of the deployer, unique design features, and lessons learned from development through testing. Introduction BRITE Constellation is a group of scientific nanosatellites whose purpose is to study oscillations in the light intensity of the most luminous stars (brighter than magnitude +3.5) in our galaxy. The observations will have a precision at least 10 times better than achievable using ground-based observations. The BRITE (BRight Target Explorer) mission formed by Austria, Canada and Poland will send to space a constellation of six nanosatelites, two from each country. BRITE-PL satellite is based on the Generic Nanosatellite Bus (GNB) from the Canadian SFL/UTIAS (Space Flight Laboratory / University of Toronto, Institute for Aerospace Studies). The spacecraft are to use the SFL XPOD (Experimental Push Out Deployer) as a separation system. Figure 1.

The second one, BRITE-PL Heweliusz, has the significant changes – it carries additional technological experiments implemented by SRC PAS. -

WORLD SPACECRAFT DIGEST by Jos Heyman 2013 Version: 1 January 2014 © Copyright Jos Heyman
WORLD SPACECRAFT DIGEST by Jos Heyman 2013 Version: 1 January 2014 © Copyright Jos Heyman The spacecraft are listed, in the first instance, in the order of their International Designation, resulting in, with some exceptions, a date order. Spacecraft which did not receive an International Designation, being those spacecraft which failed to achieve orbit or those which were placed in a sub orbital trajectory, have been inserted in the date order. For each spacecraft the following information is provided: a. International Designation and NORAD number For each spacecraft the International Designation, as allocated by the International Committee on Space Research (COSPAR), has been used as the primary means to identify the spacecraft. This is followed by the NORAD catalogue number which has been assigned to each object in space, including debris etc., in a numerical sequence, rather than a chronoligical sequence. Normally no reference has been made to spent launch vehicles, capsules ejected by the spacecraft or fragments except where such have a unique identification which warrants consideration as a separate spacecraft or in other circumstances which warrants their mention. b. Name The most common name of the spacecraft has been quoted. In some cases, such as for US military spacecraft, the name may have been deduced from published information and may not necessarily be the official name. Alternative names have, however, been mentioned in the description and have also been included in the index. c. Country/International Agency For each spacecraft the name of the country or international agency which owned or had prime responsibility for the spacecraft, or in which the owner resided, has been included. -

This paper investigates the possibility of exploring the Martian system by using a manned spacecraft, the Crew Interplanetary Vehicle, (CIV) and a cargo vehicle, the Mars Automated Transfer Vehicle (MATV). The main payloads, carried by the high efficiency solar electric MATV, are a two-passenger spacecraft landing on Phobos; an orbital laboratory and a rover network for deployment to the surface of Mars. In order to cope with the constraints imposed for a human mission to deep space, the feasibility study has been performed using a human-centred design approach. The main output of the mission is the preliminary design of the CIV. Furthermore, the main parameters of the MATV as well as the orbital laboratory and the Phobos Lander were estimated. The manned spacecraft is designed to depart from LEO in 2036 using chemical propulsion. Once in Mars proximity, the main manoeuvres will be performed using nuclear thermal propulsion and a bi-propellant chemical system will perform the minor manoeuvres. -

Optical Co-Orbital Measurements in Low Earth Orbit
Optical Co-orbital Measurements in Low Earth Orbit by Kevin Bernard A thesis submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of Master of Applied Science in Aerospace Engineering Carleton University Ottawa, Ontario © 2019 Kevin Bernard For all the support my family has provided over the years, this work is dedicated to them. ii Abstract The increasing access to the space domain has led to the growth of the on-orbit object population, as well as the evolution of space surveillance capabilities. With the increased public attention paid to spacecraft proximity and rendezvous operations, is an opportunity to examine what and how current space surveillance capabilities can contribute to this field. This thesis examines the feasibility and challenges associated with re-purposing an existing on-orbit space surveillance capability, the NEOSSat microsatellite, to per- form proximity operations. The ability of NEOSSat to collect a sufficient number of accurate optical observations to determine the relative orbit of a target spacecraft is explored. A variety of observation events are explored with a collection of space- craft to generate relative orbits using inertial orbit determination techniques. These practical results, to the author's knowledge, are the first in the field of relative or- bit determination using inertial techniques between two co-orbital Low Earth Orbit satellites. iii Acknowledgements I would like to sincerely thank my supervisors, Dr. Steve Ulrich and Dr. Lauchie Scott. Thank you Steve for providing guidance, and for taking a chance on someone who walked in to your office in the Spring of 2016.
