Planetary Frequency Beacon(s)! - Track ALL the things!

While I wasn't quite sure which section to put this under, I figured this one would do, since it deals with planets!
(If it's wrong, then I'm sorry!)

While I do have a notepad file of coordinates and planets with important things (werehouse planet, apex/prison/floran/etc. planets, planets with towns/airships and so forth!) I think it'd be much nicer to provide a visual cue, able to be seen on the Starmap itself!

To this, I suggest a "Planetary Frequency Beacon" ~ A place-able item that looks very similar to the Distress Beacon in terms of appearance (satellite dish!), but works very differently:

Currently, the Starmap includes a beacon above a planet if it's your current location, while a house icon under the planet if it's the player's home. Beyond that, if you've been roaming and not writing, there's no way to get back!

Thus, the (in theory) beginning-middle (I imagine beta/gamma and so forth) tiers of the game would grant the player the ability to craft a beacon into the ever-expanding universe! Using something involving steel and titanium, with perhaps some current-carrying items like a crafted battery, or even a Molten Core (to give repeatable reasons to take down the UFO that goes after distress beacons)

Such a beacon, if placed upon a planet, would grant the galaxy (on the galaxy starmap) a resonating green(?) pulse (or just a colored green circle for simplicity). On the planetary system (next step down), the planet with the beacon in question would have a green(?) asterisk or satellite dish icon to represent a beacon present.

But would I stop there with a thought? Of course not!

These beacons would be limited to the placing player's own grid of the universe, meaning friends and other people on the server wouldn't/couldn't troll by seeking out those planets, due to their ships not being attuned to the same frequencies (/lore-reasoning)

However, naturally I wouldn't have it end there! Looking for friends, but don't want to invite them to a party, or let them aboard your ship? Then as a bonus, craft a "Portable Frequency Beacon" which is a wearable (back-slot) item (that's a satellite-dish-on-a-stick connecting to a metal box your character wears), providing an (orange) set of pulsations/circles on the starmaps to indicate that at least one intelligent life form exists!
