SPICE Kernel Archive Description

This section describes the structure and contents of a PDS SPICE bundle following the PDS4 standard using the NAIF approach [PDS3GUIDE].

There might be some concepts and/or words used in this chapter that you might not know or understand, if so please take a look at the documents that describe the PDS4 standards. These documents are available at the PDS Data Standards Document page.

Don’t worry, everything that is specified in this chapter is implemented by the NAIF PDS4 Bundler: the idea of this chapter is to provide you background and the rationale of how and why SPICE kernel archives are implemented this way.
