{"title":"Laboratory Characterization of Optical Inter-satellite Links for Future GNSS","authors":"J. Surof, J. Poliak, R. M. Calvo, Mathias Richerzhagen, R. Wolf, Tobias D. Schmidt","doi":"10.33012/2019.17042","DOIUrl":"https://doi.org/10.33012/2019.17042","url":null,"abstract":"Optical inter-satellite links are proposed in the Kepler constellation to connect satellites in a Global Navigation Satellite System (GNNS) constellation for optical ranging, time transfer and data transmission [1]. A laboratory demonstrator is being developed to verify all three aspects. The demonstrator is constituted by two terminals, performing a bidirectional free-space optical link in the laboratory, with single-mode fiber coupling in the receivers at both sites. The optomechanics is based on commercial off-the-shelf (COTS) components. The optical terminal includes a point-ahead assembly, which compensates for the point-ahead angle (PAA) between the two linked satellites. The absence of the PAA under laboratory conditions allows this mirror to be used for pointing jitter emulation instead, i.e. to emulate the expected satellite platform angular vibrations. The ranging is performed by using a 25.55 Gc/s binary phase shift keying (BPSK) phase modulation of the optical carrier. This high modulationrate allows ranging accuracy in the order of 100 µm. The data-communication channel is multiplexed to the ranging signal at a rate of 50 Mb/s and allows exchanging satellite and timing information. Both the optical carrier and the spreading sequence are synchronized to the on-board reference and a reference clock input for the sequence generator Field Programmable Gate Array (FPGA) is generated. Thus, the information exchanged though the data communication channel and precise ranging are used to support highly accurate two-way time transfer between the linked satellites. The objective of this paper is to present the hardware developments of optical terminals, which will demonstrate range measurements and communications. The first characterizations of the main terminal components are shown, namely the real-time Digital Signal Processing (DSP) system based on FPGA for ranging and data transfer and the optical phase-locked-loop (OPLL) for locking and tracking the incoming optical carrier. Further, static homodyne ranging estimation is evaluated and the impact on the frequency stability of the optical assembly and other main components is shown.","PeriodicalId":381025,"journal":{"name":"Proceedings of the 32nd International Technical Meeting of the Satellite Division of The Institute of Navigation (ION GNSS+ 2019)","volume":"1993 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128633551","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}

Position accuracy, high availability, robustness of operation and formal integrity of the observables are the priorities, which are giving rise and shaping a new class of automotive receiver components and architectures. Moreover, because the autonomous driving and ADAS are safety critical, on top of previous requirements there is also the requirement for Functional Safety (informally called FuSa) compliancy. The documents codifying Functional Safety for automotive are the ISO26262 part 1 to part 11. The ISO26262 complements the well-known reliability automotive standard AEC-Q100. With respect to FuSa, a system can be defined as functionally safe if it always operates correctly and predictably. More importantly, in the event of failures, the system must remain safe for persons. Lastly also security is becoming a paramount and a new standard for cybersecurity in automotive, the ISO/SAE 21434, is in development where for a GNSS receiver this means robustness versus jamming, spoofing and meaconing attacks. This contribution introduces the functional safety and the security aspects of the new STMicroelectronics TeseoAPP (STA9100) GNSS receiver chipset.","PeriodicalId":381025,"journal":{"name":"Proceedings of the 32nd International Technical Meeting of the Satellite Division of The Institute of Navigation (ION GNSS+ 2019)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128690953","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}
