Talk:DRADIS/Archive 1

I've always thought it was similar to the US Navy's Aegis Mk VII system. Panther 20:54, 17 August 2006 (CDT)

There's a definite RDM blog answer that's about a sentence long and says it's a different word for radar.

Something else is very similar to Aegis, though... I think it's in a battlestar article, probably a point-defense item for obvious reasons. --CalculatinAvatar^(C-T) 01:06, 18 August 2006 (CDT)

It is stated that DRADIS stands for 'Direction RAnge and DIStance'.

Should it not be 'Direction RAnge Detection and Identification System' This still has the acronym DRADIS?

I'd be happy to see a source for this term; I'd rather not make it up if RDM has the acronym down. He's normally not into this inane level of techno-fanboy detail, so we'll have to see. Better to keep this one to what we know. Spencerian 15:54, 23 Aug 2005 (EDT)0

Agreed, FWIW. --Peter Farago 17:43, 23 Aug 2005 (EDT):

We need a definite and official source for what this term means. Personally, I don't believe that it is well defined, if at all. -- Joe Beaudoin 20:30, 23 Aug 2005 (EDT)

It adds nothing to the debate :), but when i heard the anacronym DRADIS, i instantly though "oh cool, thats Direction, Range AnD Identification System ...good to see someone is thinking hard about all the little stuff"

To me it makes sense for it to mean this...remember the first few eps of ST didnt have Starfleet, but the United Earth Space Probe Agency or some such....ID it is! Hooray! :) And i'd write it as Dradis..like Radar..the caps dissapear after a while :) --Simmons 07:36, 1 February 2006 (EST)Simmons

"Range" and "Distance" are indeed redundant in their most common sense, but in space, a system like this would be pretty much pointless if it didn't provide directional information in two axes, as well as the distance. Even without a useful expansion of the acronym, it should be abundantly clear that these would be the three values present in the reading for a single DRADIS contact. -- Cmr

Indeed, Gaeta has given three-value coordinates when it's been relevant — in Act of Contrition and Resistance.

Just an interesting note - Bearing and Carom are clearly not measured in degrees. We've seen bearings up to 881 (Tigh Me Up, Tigh Me Down) and caroms up 552 (Flight of the Phoenix). --Peter Farago 14:38, 5 January 2006 (EST)

Another interesting note - The Army in its land navigation uses a method of measurement called the mil [[1]] which breaks a circle up into 6400 parts rather than 360. That may explain the higher numbers quoted. Joemc72 15:01, 19 January 2006 (EST)

"Range" and "distance" are still synonyms in 3 dimensions. Yes, there are 3 numbers for spherical coordinates, but 2 of them are direction; the other one is range (and distance, since they're the same thing). --CalculatinAvatar 23:29, 5 January 2006 (EST)

I understood your point the first time, and wasn't trying to contradict it. --Peter Farago 23:39, 5 January 2006 (EST)

If you're addressing me, I'm somewhat confused. I don't recall saying that before, and I was responding to Cmr. --CalculatinAvatar 00:07, 6 January 2006 (EST)

my point is just that this article can describe what DRADIS measures, and how, without expanding the acronym. is the early teleplay manuscript the only source for Direction, RAnge, and DIStance? if so, it seems like this is, at best, something less than canonical. Cmr 17:35, 15 January 2006 (EST)

Another (possibly unhelpful) speculation. DRADIS might be expanded usefully to 'Direction RAdius and DIStance.' This would provide the bearing to target (in three-space), the distance to target, and the radius (radians?) of the target at that distance - either the equivalent of the radar cross-section or signal strength, or perhaps some other actual size measurement which could be used to determine the target's identity? --sierran 12:35, 21 February 2006 (EST)

I think that sierran is closest: I believe it's either (Direction, RAdial, DIStance) or (Direction, RAdian, DIStance). I'm not sure of the origin of the original interpretation, but if it's not from quotable dialog, it's probably incorrect. Spherical coordinate systems require three values, but different names are used in various contexts: (radial, azimuth, polar), (radial, azimuth, zenith), (range, azimuth, elevation). In the first two sets, "radial" is the distance from the point of origin, but a radial pattern is a one that appears to originate at a point, like spokes in a wheel. A scriptwriter could easily substitute RAdial into an acronym, without realizing it is technically incorrect. Substitute DIrection for azimuth and DIStance for range, and it yields what I think is the intended derivation. Alternatively, RAdian is a unit of plane angle. Although both azimuth and elevation can be expressed in radians, perhaps a scriptwriter chose it for elevation because it created an acronym that sounded cool. --ptb 11:49, 12 March 2006 (CST)

I have a WAY WAY WAY better definition for the DRADIS acronym. Get this. Get this, it's awesome. You ready? Check this out: Direction RAnge DISplacement. "Displacement" is commonly used in Naval terms to describe the amount of water mass "displaced" by a ship. Displacement could easilly be co-opted for this sort of "Space Navy" mentality to be used to define the size of ships on DRADIS. Notice that DRADIS does make a distinction between the small vessels and the capital ships. Obviously it's more than a direction/distance calculation. So what do you think? Direction RAnge DISplacement? Eh? Eh? I think it's high quality. --Trajan 21:47, 26 October 2006 (CST)

Radar

Spencerian, why did you revert Wingsandsword's note about the "radar" reference in "The Hand of God"? The dialogue in question goes like this:

Thrace: The decoy ships will jump into the enemy star system at extreme radar range from the Cylon asteroid. Galactica will jump here, close enough to launch its Vipers at the base.

--Peter Farago 12:07, 10 January 2006 (EST)

There has been some healthy discussion of this point on my talk page, and for the record it is at 11:53 into the episode, and her exact line is what Peter Farago said it was. It's also on the closed captioning. It's likely to be a goof, but it could be interpreted that "radar" is a slang or mostly-disused term for the more technically accurate Dradis. --Wingsandsword 14:37, 10 January 2006 (EST)

Her "exact line" is still subject to debate: DVD subtitles aren't always reliable, and when I saw it again on my DVD it sounded like she said "Raider", not radar. "Radar" probably isn't a slang term because I think they're more careful about these things and that it is not, indeed a goof. Others please rewatch this scene. I'm not exact on how all DVD subtitles are made, but on many I've had in the past they were really just made by people that watched the episode writing down dialog, rather than on a script of some form. They aren't really reliable. --Ricimer 21:06, 10 January 2006 (EST)

What if RADAR is one component of DRADIS? Suppose that DRADIS comprises a host of detection systems (RADAR, IR, UV, MAD, etc.) all linked into one system and accessed from one console?--Axeman

As I have stated numerous times, in context, she could have been saying "Raider range". There's a burden of proof there, a shaodw of a doubt if you will, and she kind of slurrs it; doesn't sound quite like she's saying "Radar". I think our current thing is fine: making a note that we think she said Radar, but that she could have said "Raider". This is, of course, distinct from the horrible "Black Market" in which amongst other failures they call fumarellos "cigars". --Ricimer 14:19, 29 January 2006 (EST)

That wasn't an error. Cigars have never been called Fumarellos in RDM. --Peter Farago 15:03, 29 January 2006 (EST)

There seems to be a lot of contention over this point. Can someone find a specific reference where they were or weren't called cigars or fumarellos? --BMS 15:09, 29 January 2006 (EST)

Actually I was just using that as an example; Peter and I are actually leaning towards the position that they were ALWAYS called "Cigars" but "tobacco" is "fumarello leaf" here.--Ricimer 15:32, 29 January 2006 (EST)

Just a comment - Astronomy uses a coordinate system that uses Declination and Right Ascension to pinpoint astral bodies. If you include distance, you now have a system that you can use to determine another objects position in space *relative to you* (if I call my "up" north, then I can place everything by how many degrees "north" (or by using negative numbers how far "south") it is, how many degrees "right" (or "left") it is, and how far away from me it is)

Name?

Should the name of this article be all caps, or is there a naming convention in place that restrits all caps in an article title? Joemc72 16:41, 20 January 2006 (EST)

Possible, but generally it looks a bit garrish and we don't know the acronym fully. Besides, do you always write out radio as "RADIO"? It's a portmaneau, not a full acronym. --Ricimer 16:49, 20 January 2006 (EST)

I agree, but throughout the article and other articles, DRADIS is capitalized. I was only suggesting it in order to make it more uniform. I'll defer to the majority though. Joemc72 16:52, 20 January 2006 (EST)

The capitalization is because DRADIS is an acronym, like RADAR or LASER or NASA. Usage for these terms have dropped the capitalization down to where the acronym becomes a word except for NASA. DRADIS isn't there yet in my mind. On the other hand, if I see it without capitalization, I don't change it unless it looks aesthetically wrong. Acronyms should be capitalized unless there is a wiki convention that says otherwise. For wiki's sake, keeping it not capitalized (particularly as the article name) prevents weirdness. --Spencerian 17:34, 20 January 2006 (EST)

To bring this subject back up, the first thing I thought of when seeing this article was that it wasnt in capitals. You are right in that people casually dont say RADAR in capitals when writing because it one of the exceptions to the rule. The word "Radar" is now officially in the English language as a standard word, theorfor losing the capitalisation in the process. Laser is also another example of an acronym adopted as an official word. Radio as far as i know was never an acronym? It seems to me that an acronym only loses its capitalisation when it becomes an official word (radar, laser, scuba etc) and when its not all letters are in capitals (ICBM, LCD, AIDS etc) --Mercifull 06:01, 3 April 2006 (CDT)

Rank

In the last frame before the opening credits in "Pegasus" the Dradis icon for the Pegasus is shown with two stars next to it. I assume these denote the rank of the flag officer (Admiral Cain) aboard. Is this worth including? Jagaroth 05:08, 13 September 2006 (CDT)

Maybe. Is there a DRADIS shot of what Galactica looked like on Pegasus DRADIS? If there isn't any special marking for Adama (of Commander rank then), we'll know that DRADIS can be configured to indicate battlestars with flag officers, as Cain was. --Spencerian 07:26, 13 September 2006 (CDT)

I think the second picture on the page is the view from Pegasus to Galactica because Galactica is in mid-field on the display rather than being the source (at the bottom). I'll check later. To confirm we'd need a shot of an external DRADIS after Adama gets promoted. Jagaroth 03:57, 14 September 2006 (CDT)

I attached the pics together, the other one is Galactica from Pegasus and there is no stars next to the Big-G. --Talos 04:43, 14 September 2006 (CDT)
