The spaces that the wires must be fit into are very small, making it difficult to maneuver and secure them. This can lead to delays because connecting the wires is time-consuming and insecure connections can lead to ground test failure. It also cannot be fully-completed ahead of time as the altimeters must be re-wired between ground test and launch. Previous solutions have involved positioning the altimeters on the sled such that the connections are easier to access and using crimps to speed up the connection process. However, even with good altimeter placement, it can be difficult to position the wires. Recovery also had issues in creating secure connections to the crimps and did not consider them reliable enough for launch. ## New solution Recovery plans to solder short lengths of wire directly into the altimeters at one end and into a crimp at the other. The end with the crimp could then be easily connected to a longer wire for ground test or flight, saving time at launch. Soldering into the crimp should increase the security of the connection, preventing the previous problems associated with crimps. This solution allows recovery to change the wiring of the altimeters, despite soldering a wire permanently into the altimeter because the long wire going to the other connection point is replaceable. Solutions involving solder were previously not considered because of the requirement of reconfiguring wires at launch. ### Schematic ![Schematic of wire connections to altimeters](https://docs.google.com/drawings/u/0/d/ssbCHd0Z-beNUC5oA4OWesg/image?w=624\&h=212\&rev=558\&ac=1\&parent=1nLnYds5rneNyQhFM1VKudWClpzfYLBrcd6UvO9CBkKM) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://rocketry.gitbook.io/public/previous-projects/pinkbeary/altimeter-wiring-update.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
