A small control electric card on one PCB (Printed Circuit Board) board is developed and packaged with ring laser in the same case, on which all functions are integrated. With heat design, the influence to ring laser is minimized. A navigational grade digital laser gyroscope (DLG) solution is developed, with bias stability better than 0.01 ° /h, size of Φ85×45 mm, weight of 410 g, power consumption of 1.6 W (+15V/+5V power supply) and RS422 interface and top bolted package. And miniature INS with position accuracy of 0.8 Nm/h and weight around 6 kg is also developed with them.","PeriodicalId":402172,"journal":{"name":"2017 DGON Inertial Sensors and Systems (ISS)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123128554","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}

Attitude computation can be achieved by integrating the angular velocity measured by gyroscopes, the accuracy of which is crucially important for the dead-reckoning inertial navigation. The state-of-the-art attitude algorithms have unexceptionally relied on the simplified differential equation of some kind of kinematic vector, such as the rotation vector, to obtain the attitude. This paper proposes a Functional Iteration technique using the Rodrigues vector (the so-called RodFIter method) to analytically reconstruct the attitude from gyroscope measurements. The RodFIter method is provably exact in reconstructing the incremental attitude as long as the angular velocity is exact. Notably, the Rodrigues vector is analytically obtained and can be used to update the attitude over the considered time interval. The proposed method gives birth to a novel attitude algorithm scheme that can be naturally extended to the general rigid motion computation. It is extensively evaluated under the attitude coning motion and compares favorably in accuracy with the mainstream attitude algorithm.","PeriodicalId":402172,"journal":{"name":"2017 DGON Inertial Sensors and Systems (ISS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131319882","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}
