From Boris.Semenov at jpl.nasa.gov Mon Apr 17 04:16:23 2023 From: Boris.Semenov at jpl.nasa.gov (Boris Semenov) Date: Mon, 17 Apr 2023 04:16:23 -0700 Subject: [Spice_announce] open seats at the upcoming June 6-8, 2023 SPICE class at ASU, Tempe, Az Message-ID: <5519b7ff-c0d8-267f-87c6-53391eaf54a4@jpl.nasa.gov> NAIF announces that there are still a few open seats available at the next SPICE training class that will take place at Arizona State University, Tempe, Az on June 6-8, 2023. This will be a traditional beginner's SPICE class with the agenda similar to the last class in October 2022: http://naif.jpl.nasa.gov/pub/naif/misc/tmp/WS2022/Tutorials/PDF/Individual_tutorials/00_WS2022_Agenda_Final.pdf Seats at the class are available to anybody who is interested on "first come, first served" basis until they fill up. As all previous SPICE classes, this class is free but students are responsible for their travel expenses. Please contact NAIF Manager if you or any of your colleagues have interest in attending this class. From Boris.Semenov at jpl.nasa.gov Mon Apr 17 13:06:01 2023 From: Boris.Semenov at jpl.nasa.gov (Boris Semenov) Date: Mon, 17 Apr 2023 13:06:01 -0700 Subject: [Spice_announce] New WebGeocalc Version 2.6.1 In-Reply-To: References: Message-ID: <4b5981f9-fc63-afdf-37b0-412268794daa@jpl.nasa.gov> NAIF is pleased to announce the deployment of the new WebGeocalc (WGC) Version 2.6.1 (5247 N67 13-APR-2023) on both NAIF's WGC servers: https://wgc.jpl.nasa.gov:8443/ (GUI only) https://wgc2.jpl.nasa.gov:8443/ (GUI and Web API) This new version adds a new Tangent Point calculation and support for Azimuth/Elevation/Range (AZ/EL/R) coordinates both in WGC GUI and in the WGC Web API. The Tangent Point calculation computes the point on the ray nearest to the target's surface modeled as an ellipsoid, the point on the target's surface nearest to the tangent point, and a few additional parameters such as illumination angles (incidence, emission and phase), time and local true solar time at one of these points. The locations of both points are optionally corrected for light time and stellar aberration, and may be represented using either Rectangular, Ra/Dec, Planetocentric, Planetodetic, Planetographic, Spherical or Cylindrical coordinates. The support for the Azimuth/Elevation/Range coordinates has been added to various WGC calculations including: -- calculations optionally requiring users to input a location or a direction vector (State Vector, Angular Separation, Pointing Direction, Surface Intercept Point, Tangent Point, Surface Intercept Event Finder, and Ray in Field of View Event Finder) -- calculations requiring users to select an output coordinate system, if the AZ/EL/R system is applicable (State Vector and Pointing Direction) -- geometric event finder calculations requiring users to specify a coordinate condition, if the AZ/EL/R system is applicable (Position Event Finder) For more information about WGC, including tutorials and usage examples, please see https://naif.jpl.nasa.gov/naif/webgeocalc.html.
