BS ISO 18197:2015 pdf free.Space systems一Space based services requirements for centimetre class positioning. BS ISO 18197 defines the requirements for the wide area centimetre class positioning system by broadcasting augmentation data through satellites as follows. — Centimetre class positioning According to the progress of requirements for positioning services such as automatic farming, mapping and others, centimetre class positioning is very useful. — Wide area positioning It is quite effective to broadcast augmentation data through satellites for users over wide area such as a square, more than 1,000 km each side, anytime and anywhere. Even if this area is short of data network, additional ground network facilities are not needed. In addition, as ranging signal and augmentation data can be received from satellite broadcasting at the same time, it is unnecessary for user terminals to receive the signal such as transmitted by ground network. — Real-time property The user terminals need to resolve the ambiguity in real-time, using augmentation data broadcast from satellites or other means, for the realization of centimetre class positioning. On the other hand, the provider sides have to broadcast augmentation data such that the terminal sides are able to resolve the ambiguity in real-time. 2 Normative references…

ISO 20188-2018 pdf free.Space systems—Product assurance requirements for commercial satellites. 5.10 Organizational capability aspects At least, prime contractor shall be certified to the applicable space standards (e.g. AS 9100, EN 9100 or JIS Q 9100) or equivalent standards. The certificate of registration or a current conformity status relative to the standards will be closely monitored by prime contractor’s PA team. 6 Quality assurance 6.1 Quality assurance program As part of the PA program, the contractor shall document and maintain an effective and timely quality assurance program in accordance with ISO 27025 or equivalent standards (e.g. Reference [29]). which will be planned in conjunction with other project functions. Quality program shall be implemented in a manner which permits the detection and correction of deficiencies and other associated non. compliances at the earliest practical point. Inclusion of provisions for ascertaining product quality from procurement through fabrication and testing, and the delivery of the completed deliverable system, as well as launch activities, shall be incorporated. Quality assurance program shall provide recorded evidence of quality in the form of inspection and test results as well as systematic audit findings. This record shall be documented in sufficient detail, accuracy and completeness to permit analysis. Records…
