Project Irazú was an innovative space mission that aimed to propel the advancement of the aerospace sector in Costa Rica, by developing a ground to space communication solution for daily monitoring of carbon fixation in forests and tree plantations. Irazú is Central America’s first satellite mission and is a joint endeavor between the Central Ameri...

GWSat is a project led by George Washington University in collaboration with the Costa Rica Institute of Technology and the United States Naval Academy. It uses a 3U CubeSat to test GWU's Micro-Cathode Arc Thruster technology developed at GWU's Micro-Propulsion and Nanotechnology Laboratory. This CubeSat will have two advanced attitude control syst...

An SGL Pathfinder relays instrument calibration data from in situ, before a flagship interstellar mission launches. Fig. 1 Trajectory Simulation, Centaurs to SGL Fig. 2 Photon-Conversion Radioisotope Battery Fig. 3 Solar Wind Speed vs Distance Trajectory Design: The trajectory to the Trappist-1 Solar Gravity Lens (SGL) was initially modeled in an i...

The Jupiter Observing Velocity Experiment (JOVE) is a solar-powered technology demonstration of rapid flight to outer solar system targets, performing a flyby of Jupiter 30 days after launch. This is achieved using a magnetic drag device to accelerate with the solar wind plasma. This “Wind Rider” propulsion system can potentially also decelerate ag...

For many years, a manned mission to Mars has been a challenge for humanity. However, the recent technological advances in human factors and space systems engineering may overcome these limitations. Thus, there are some strategies to face various medical emergencies autonomously due to long distances and hostile conditions in order to develop health...

Costa Rica became a space nation in 2018, with the launch of the CubeSat "Project Irazú". Also, in 2016 the Costa Rica Aerospace Cluster was created with the objective of strengthening the capabilities of the companies working in aerospace engineering, an industrial area of very high added value. The Space Systems Engineering Laboratory (SETEC Lab)...

The aim of this paper is to present a novel control strategy of the satellite attitude control problem on an energy-based setting, more specifically on the port-Hamiltonian framework. Controlling the orientation of a satellite becomes challenging in presence of nonlinear external disturbances such as the gravity-gradient torque and the atmospheric...

Spacecraft orbit and attitude dynamics have been classically seen as two separated subjects, since the effect of attitude in orbit dynamics was deemed too small to be considered, or simply, modeled as noise in the estimation process for most satellites. In the eighties, a study by Chodas showed that for a very large spacecraft, approximately the...

The increasing number of Cubesat launched during the last ve years o er an opportunity of learning and optimizing satellites operations through the collection, analysis and use of their flight performance data. Global networks of ground stations, for instance, SATNOGS allow users from all around the globe to collect, store and regularly share satel...

Since the eighties, when the first Costarrican-born NASA astronaut Franklin Chang went to space, there has been efforts to take advantage of the Costarrican biodiversity and its commercial applications for human spaceflight. Experiments related to the cure of Chaga’s disease were performed on that time from a cooperation of Dr. Chang and universiti...

Costa Rica is known worldwide for its efforts regarding conservation and utilization of environmental resources, which have been considerably affected over the last few years due to climate change. To aid the country’s efforts on environmental preservation, the Small Satellite Program for Environmental Monitoring (SS-PEM) was created at the Space S...

Costa Rica is world-renowned for its environmental conservation and its clean energy generation. The government-led programs such as the Environmental Services Payment Program has resulted in an increase of the country's forest coverage from 21% in 1987 to 51.4% in 2010. Additionally, the country has established an ambitious goal of becoming a carb...

The Costa Rican space program has expanded after the Irazú CubeSat, the first Central American satellite, was successfully developed. The main mission is to demonstrate a Store Forward (S&F) System that enables transmission of biomass and carbon dioxide fixation data from a remote fast growth tree plantation in the north of Costa Rica, to a researc...

The Latin American region has embarked on different endeavors related to space engineering in recent years. For example, Costa Rican and Guatemalan CubeSat missions are currently being independently developed with the main purpose of developing human capital, creating the know-how, and infrastructure necessary to execute end-to-end space missions....

The Costa Rica Institute of Technology (TEC), in cooperation with the Central American Association for Aeronautics and Space (ACAE), developed the first Central America Satellite: Project Irazú. This satellite is a one-unit (1U) CubeSat that works as a store-and-forward (S&F) system, transmitting the information of ground sensors measuring tree gro...

In this work the extent to which orbit and attitude sensors may cross-support each other in a joint processing to reduce estimation errors of the relative orbital and attitude dynamics is investigated. In order to do this, an engineering dynamic model taking into account the coupling effects between orbit and attitude dynamics is exploited for esti...

In 2007, the Government of Costa Rica announced to the world its ambitious goal of turning into the first carbon neutral country by 2021. Following the announcement, governmental institutions, universities, NGOs and private companies have worked arduously on the creation of different initiatives to reach that goal. One innovative project is Irazú,...

The Central American region has embarked on different endeavors related to space engineering in recent years. CubeSat missions are currently being independently developed in Costa Rica and Guatemala, with the main purpose of training the human resources, creating the know-how, and infrastructure necessary to execute end-to-end space missions. On th...

In this work we investigate to what extend orbit and attitude sensors may cross-support each other in a joint processing to maximize information retrieval of the relative orbital and attitude dynamics. Its contribution clarifies to what extend the coupling effects between orbit and attitude dynamics can be advantageously exploited for estimation pu...

The Costa Rica Institute of Technology (TEC) and the Central American Association of Aeronautics and Space (ACAE) are currently developing the Irazú project, which consists of using a 1U CubeSat to demonstrate the capacity of a Store and Forward system for the transmission of environmental data from a remote region in Costa Rica to a data processin...

The Costa Rica Institute of Technology (TEC) is currently building the first Central America Satellite in partnership with the Central American Association for Aeronautics and Space (ACAE). The CubeSat project known as Irazú was proposed to show the existing capacity to develop a complete space project in Costa Rica and to enhance space systems eng...
