1. 1. Testing for verification and validation of an onboard orbit determination system exploiting GNSS : A nanosatellite application for HERMES-SP

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Clara Nermark; [2023]
   Nyckelord :Onboard orbit determination system; GNSS; nanosatellite; testing; verification and validation; Ombord banbestämning; GNSS; nanosatellit; testning; verifikation och validering;

   Sammanfattning : When developing products for space, including nanosatellites, the verification and validation process is a mandatory part of any project conducted within the European space industry. Within such a process, testing is a method for verification and validation. LÄS MER

3. 2. Feasibility study of initial orbit determination with open astronomical data

   Master-uppsats, KTH/Fysik

   Författare :Linn Mattsson; [2022]
   Nyckelord :Space situational awareness; Space surveillance and tracking; Image analyse; Streak detection algorithm; Initial orbit determination; Rymdlägesbild; Bildanalys; Algoritm för streck detektering; Initial banbestämning;

   Sammanfattning : In this report I present a feasibility study of using open astronomical data to make Initial Orbit Determination (IOD) for Resident Space Objects (RSO) appearing as streaks in telescope images. The purpose is to contribute to Space Surveillance and Tracking (SST) for maintaining Space Situation Awareness (SSA). LÄS MER

4. 3. Space Situational Awareness with the Swedish Allsky Meteor Network

   Master-uppsats, Uppsala universitet/Observationell astrofysik

   Författare :Simon Alinder; [2019]
   Nyckelord :SSA; space situational awareness; IOD; initial orbit determination; orbit determination; satellite identification; all-sky; rymdlägessituation; SSA; omloppsbana; banbestämning;

   Sammanfattning : This thesis investigates the use of the Swedish Allsky Meteor Network (SAMN) for observing, identifying, and determining the orbits of satellites. The overall goal of this project is to determine the feasibility of using such a network for Space Situational Awareness (SSA) purposes, which requires identification and monitoring of objects in orbit.

5. 4. Kinematic orbit determination of low Earth orbiting satellites, using satellite-to-satellite tracking data and comparison of results with different propagators

   Master-uppsats, KTH/Geodesi och geoinformatik

   Författare :Muhammad Zaheer; [2014]
   Nyckelord :GPS; Orbit Computation; STK; SGP4; HPOP;

   Sammanfattning : The GPS data from Challenging Mini-satellite Payload (CHAMP) is used for its orbit determination for the epoch day of January 1st 2002.  The orbit of CHAMP is computed from the GPS data and ionospheric effects are removed by frequency combination. LÄS MER
