The Lunar Reconnaissance Orbiter (LRO) collects around 573 GB of data per day and the data is sent to the ground station (WS1) located in White Sands, New Mexico [1]. The LRO communicates with the earth station an average of 4 times per day throughout the year [2]. The LRO has several instruments in the lunar orbit, ranging from passive imagers to an active altimeter, as well as a synthetic aperture radar [2]. There is a growing need to transfer more data to the earth station for future missions. In order to accomplish this goal, we propose to use a CubeSat relay between earth and the moon orbiter. This CubeSat will communicate with the deep space network (DSN) instead of communicating with WS1 and this will help in improving the connection time between the moon orbiter and ground station. The data rate of the proposed method would be 4.5 Mbps with binary phase shift keying (BPSK) modulation.","PeriodicalId":188904,"journal":{"name":"2021 IEEE Space Hardware and Radio Conference (SHaRC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114945478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The array utilizes Anokiwave RFICs (AWMF-0117) which provides flat panel integration of the beamforming network with the antenna aperture.

The cost and complexity of data converters are a significant concern with systems having hundreds of antennas. This paper explores frequency division multiplexing as an approach for augmenting the baseband signals of multiple antenna channels such that a single ADC can sample a multitude of antennas in an array. The approach is equally applicable to both massive MIMO and mm-wave digital wireless arrays. An example design based on Xilinx RF SoC for combining 4 antenna channels at 28 GHz into a single ADC is provided.","PeriodicalId":188904,"journal":{"name":"2021 IEEE Space Hardware and Radio Conference (SHaRC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131447268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Functional testing of DREX units can be challenging due to their complexity. This is true for lab testing but is especially true for field testing. This work describes a method for testing that uses a loop back approach. Three loop back tests are described which essentially involves one or more signals from transmit channels routed to one or more receive channels. An example digital receiver exciter is described along with the data converters and field programmable gate array. The loop back test method is then described, and a Python program is developed that simulates the approach. Initial testing of the receive section is then presented.","PeriodicalId":188904,"journal":{"name":"2021 IEEE Space Hardware and Radio Conference (SHaRC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133031851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The updated ground station concept for this mission is motivated and outlined. Following, the concept of the hardware and software design of the ground station as well as the operational principle are described. The nowadays often used concept of using Software Defined Radio (SDR) for small satellite ground stations is applied here and its benefits for a formation flying mission are analysed. Our concept of taking advantage of the SDR is further outlined. First tests of the implemented parts are performed during Launch and Early Orbit Phase (LEOP) and show benefits during this critical phase. In addition, an outline of future steps in developing and implementing the concept is given.","PeriodicalId":188904,"journal":{"name":"2021 IEEE Space Hardware and Radio Conference (SHaRC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125435214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the noise level in orbit is relatively high in the frequency bands used. Therefore, the upload of high amounts of data, e.g. software updates, can take a long time. Especially in case of satellite formations where updates need to be delivered to multiple satellites. We propose to make use of wireless broadcasts, rateless codes, and adaptive tracking algorithms to implement efficient data uploads to satellite formations. In this paper, we present appropriate algorithms and evaluate their performance for the CloudCT satellite formation scenario by discrete-event simulations based on detailed models of the system and in-orbit measurements.","PeriodicalId":188904,"journal":{"name":"2021 IEEE Space Hardware and Radio Conference (SHaRC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116198368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the design paradigm is shifting from multiple-year design and development of payload using customized devices, to rapid design and prototyping using commercial-off-the-shelf (COTS) components, end-to-end testing is essential to ensure success of the mission. Thermal-vacuum (TVAC) testing is one of the key tests performed on the lunar systems. TVAC testing is an experiment to verify the readiness of the hardware and software under the extreme circumstances the payload will experience in the space environment. This paper focuses on the TVAC testing of a hypothetical small wireless lunar sensing payload's communications system, consisting of an electrical power and communications subsystems, on-board computer, and housekeeping and scientific sensors. The experiment follows NASA guidelines and standards to confirm the design requirements and their verification plan. The payload is considered part of a short-duration sensing and telemetry mission in a particular location near-Lunar-surface environment. Therefore, it is designed to withstand the computed thermal and vacuum requirements for the mission conditions: a temperature range from 15° $C$ to 50° $C$ and an atmospheric pressure of $10^{-4} Pa$.","PeriodicalId":188904,"journal":{"name":"2021 IEEE Space Hardware and Radio Conference (SHaRC)","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114342190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
