This group covers deep space navigation, stellar cartography and vessel helm operations. It's for anyone interested in how we get where we need to go and how we get around once we're there.

Updates to Cruise Mode

Submitted by Chief_Sonya on July 13, 2020 - 23:05

The helm has been updated with latest data from engine simulations, with some significant changes to vessel handling.

It turns out the helm was significantly under-reporting EM output from helm maneuvers in cruise mode. The changes mean that achieving the maximum bearing for a given speed will require100% thrust - and 100% EM output. So to reduce EM output during a helm maneuver in cruise mode, best to select a smaller bearing (for example a bearing that is 60% of the maximum available bearing will only require 60% thrust to achieve).

Held Bearing Execution

Submitted by Chief_Sonya on March 9, 2020 - 23:06

Here's an interesting article: a guide to executing held bearing meaneuvers, such as the radial traversal (partial planetary "orbit") seen in the recently post evolution video.

Deceleration Charts

Submitted by Chief_Sonya on February 12, 2020 - 10:38

Impulse deceleration charts have been posted here. These provide a useful guide for when you have to stop at a particular spot.

You should always bear in mind that there's no such thing as pinpoint accuracy with impulse nav, so these charts aren't accurate to the GU. For starters, your actual deceleration distance will depend on when in the maneuvering cycle you push the engage button. But they should be good for +/-50GU.

Helm Update

Submitted by Chief_Sonya on January 12, 2020 - 21:21

Some great new improvements have been included in the latest update to the helm, including a couple we’ve been asking after for a while.

Think you can fly this course?

Submitted by Chief_Sonya on January 9, 2019 - 22:43

Our first navigation evolution (training and evaluation exercise) was recently posted. It's still pretty bare-bones at the moment but it gives a great idea of what's required to pilot a ship like Endeavour around.

Civilians getting close to our nav tech?

Submitted by Chief_Sonya on January 15, 2018 - 21:05

Interesting article on "x-ray navigation" that sounds similar to our deep-space nav systems:

Navigation Reference

Submitted by Chief_Sonya on December 7, 2017 - 14:48

Reference material for navigation has been posted in LIAIS, which has been written to support training and operations. The current material covers impulse (sublight) navigation, which is the mode where most combat will happen (for example).

This is a good place to start: http://crew.isdc.network/liais/navigation/navigation-overview-574 or through the main menu at TECHNOLOGY > VESSEL SYSTEMS > NAVIGATION.

Navigation Grid Orientation

Submitted by mattm on November 21, 2017 - 11:44

Details of the vessel's navigation systems and the technical framework they use will be published soon. One issue that has arisen is around the orientation of the 3D Cartesian grid used for navigation, which seems less suited to describing movement when you're inside a vessel rather than looking at it from some external viewpoint.

Navigation Terminology

Submitted by mattm on November 8, 2017 - 18:35

Propulsion and navigation prototype systems are being delivered and before we got too far with the associated documentations I thought this would be a good time for a debate on the terminology we’re going to use for navigation.

There are two possible sources of tradition on this: navy and airforce. Space efforts were traditionally run by the airforces of the world and so that was the source of a lot of the terminology used in space. The vessels were small and maneuvers were tight, making them more like aircraft to fly (quite literally in the case of the Shuttle).
