EMDAR Designation Changes

Some changes have just been made to the process for designating EMDAR contacts. The new system assumes multiple contacts will be used in attempts to track a target, an approach which has emerged from tactical simulations.

Narrowband EMDAR Limits

The sim has just been updated to introduce narrowband EMDAR limits. This means that a narrowband track will be lost if the range to the contact exceeds a certain distance (10K GUs +) or if the contact moves into a sensor shadow behind an AO.

Previously, the sim assumed a track was "forever" but with new modeling data coming in we now know enough to apply these limits. Which will present new tactical challenges (and opportunities)!

Tactical Overlay Added

A tactical overlay extension has been added to the contact board (including the read-only board used at the conn). The overlay provides a 2D representation of contacts (tracked and untracked) on the board.

Plot Interface for Contact Board

We've been plotting (haha) a new piece of functionality for the contacts board - a course plot display which would show the position of contacts on the board relative to the ship (as a simple schematic map).

The idea came out of the hunt sims I've been doing where I took to sketching out contacts on my tablet to get a feel for the course they might have been describing.

Sim Meetup Video

At this Sim Meetup we were doing some tuning work on tactical sensors, so it seemed like a good time to walk through how EMDAR is used to detect and target other vessels in space.

EMDAR Updates

There have been some updates to EMDAR that reflect new research data on EM dissipation. It turns out we have been over-estimating how much EM dissipates over distance, meaning EM emissions are easier to detect at lower output levels than previously thought. Which will make an EMDAR tech's life easier, but a quartermaster's life harder.

Previously only EM output above 60 SEMs were thought likely to be consistently detectable at ranges of over 3000GUs. Now, even EM output at 20 SEMs is consistently detectable (via extrapolation) at up to 7000GUs.

New EMDAR evolutions

A couple of new EMDAR evolutions (training exercises) have been published, just in time to try out in the new sim facility!

Needle in a Haystack is pretty basic. The target isn't moving and is outputting constant EM, but it gives you a feel for how to pick target bearing from the waterfall display. With only your ship moving, it's easier to correlate the waterfall drift with heading changes. Check it out here.

Evolution: Ship in a Bottle

This EMDAR evolution involves tracking a TSMO which is constrained within a set area of space. It provides training and competency evaluation on advanced interpretation of waterfall data and co-ordination with flight operations.

Evolution: Needle in a Haystack

This EMDAR evolution involves tracking a stationery TSMO that begins just on the edge of EMDAR range. It is intended to provide training and competency evaluation on interpretation of waterfall data, operation of contacts board and operation of narrowband EMDAR.
