The SGR-A1 is a type of autonomous sentry gun that was jointly developed by Samsung Techwin (now Hanwha Aerospace) and Korea University to assist South Korean troops in the Korean Demilitarized Zone. It is widely considered as the first unit of its kind to have an integrated system that includes surveillance, tracking, firing, and voice ...

2022年7月6日 · USGS Geochemical Reference Material Information Sheet for SGR-1b (Green River Shale), updated June 2022. This reference material is no longer available.

Topcon introduces the SGR-1 satellite receiver with TruPassTM advanced positioning technology for higher, stable pass-to-pass accuracies in dynamic applications. The SGR-1 features faster satellite acquisition and simultaneous processing of both GLONASS and GPS signals.

Dual-constellation (GPS + GLONASS) satellite reception for high accuracy, low down time Fast, 32-channel Universal Tracking Outputs ground speed as simulated radar for slow speed operations Features Topcon's TruPass™ advanced positioning technology

Reference materials are suitable for use in testing analytical methodologies and as quality control samples. We currently are not accepting any new FUSA applications for USGS GRMs. We anticipate restarting the program soon. Please check back for updates. Please note that we are still accepting orders on current FUSAs.

1980年1月1日 · SGR-1 has much lower REE content and higher La/Yb than the other samples. SCo-1 compares very favourably to an estimate of the average shale, for 45 elements, and is considered an excellent reference standard for geochemical studies of sedimentary rocks.

SGR-1，韩国研发出一种新型 机器人。 2014年9月，韩国将其安放在“ 三八线 ”附近，该机器人可以监视 朝鲜 的动向 [1]。 这一机器人型号为SGR-1，由韩国 三星集团 研发而成。 机器人携带有5.5毫米口径机关枪和40毫米口径 枪榴弹发射器，监视范围约为1公里。 韩国研发出一种新型机器人并将其安放在“三八线”附近，该机器人可以监视朝鲜的动向。 研发人员表示，士兵在值勤时容易睡着或精神不集中，但机器人可以随时保持警戒。 一旦发现敌情，机器人会马上向韩国指挥 …

The SGR-1 features Topcon TruPass advanced positioning technology for higher, more stable pass-to-pass accuracies in dynamic ag applications. The SGR-1 also outputs ground speed as simulated radar for improved slow speed operations such as seeding and spraying.

The SGR-1 is a single board receiver with a position update rate of 10Hz, upgradeable to 20Hz. With 32 universal channels, the SGR-1 tracks different combinations of GPS L1 C/A, code and carrier, GLONASS L1 code and carrier, as well as SBAS including EGNOS and WAAS.
