All Source. Standardized. Community Developed.
ASPN is a data standard that describes what PNT data should be exchanged for consistent usage and interoperability of PNT estimators across different systems, sources, and users.
ASPN defines navigation message content of both the PNT information sources and the PNT users. These definitions enable PNT estimators to be built using these message content definitions.
The ASPN Impact
-
Implements wider sensor support without data model modification
-
Enables application across multiple services, platforms, and systems
-
Enhances compatibility without requiring coordination
-
Sustained by community-driven innovation
PNT engineers benefit from the ability to add or remove sensors to adapt to different applications without redesigning their PNT estimation software.
