[Flightgear-devel] Re: Buildings ?????
It's not so much an issue of San Fran being BAD, it's just that KSFO is pretty far from downtown. We're talking about small slow-flying UAV's in my project (I'm using the Piper as a surrogate), so having to take off that far away means my demo is like 45 minutes long. We were hoping to use DC as Reagan National is real close to the Pentagon, the Monuments, White House, Capital, etc. It looks like we're just going to stick to San Fran for now though. No money in the project budget for me to do 3D Modeling (unless I do it on my own time) and I found that there's CA26 Heliport right near downtown SF, so we'll just start out from there. Before we do our final demo late next year I'm going to have to get some scenery/buildings built for some place like Baghdad though. Hard to show operationally relevant demos having a UAV flying around SF to a bunch of Army brass The hippies are shooting you with bongs! And now we simulate engine failure caused by the floating reefer Actually, that brings up another question Is it possible (through the Telnet/HTTP interface) to push a new value for things like fuel flow rate and such and have them stick, or will the sim just immediately overwrite the value I send in with a new value with the actual rate? I'm looking for a way to be able to simulate things like fuel leaks, or engine overheating, etc (part of our software detects potential vehicle problems and auto-replans mission routes to take into account reduced system capabilities like lower endurance due to a fuel leak).

[Flightgear-devel] Buildings?????
Hey gang, I'm using FG for some simulation of UAV flight and I need to present a demo soon to the customer. I was looking to use an urban area to fly around and demonstrate in, preferably either NY City or Washington DC. Unfortunately when I loaded up the scenery data for each of those, no buildings show up, only the terrain. Is there a way to get buildings to appear (like the wash monument, white house, pentagon, capital, etc.?) Did I load the scenery in wrong? Or is this just a glaring big black hole with the FG scenery (no building data.) I'd prefer to demonstrate somewhere other than San Fran.

Re: Re: [Flightgear-devel] 2 Questions: Terrain data? Flight Sim
Gosh I don't know, a Piper Cub UAV would be pretty impressive. :-) Michael Selig has a screenshot of one on his web page, so he might know where you can get yourself a UAV 3D model. Google uiuc selig flightgear Best, Jim Jim, I did as you suggested, and it appears he has a UAV on there, but all of the aircraft are for a VERY old version of FG (0.7.2) and examination of the files shows that they're not even close to the same sort of format that the 0.9.8 codebase uses. Bummer! Anyone else have any ideas or could they tell me how to get the predator model from flightsim.com 's file library converted over to work on FG. Heck, at this point, if somebody could do the conversion for me I might even be able to get my company to kick some $$$ your way (although we'd really prefer an even smaller UAV model, like a Raven or a Silverfox or Hunter or something like that.) --Mike ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
[Flightgear-devel] 2 Questions: Terrain data? Flight Sim 200x aircraft?
Hey gang, I'm needing to integrate with a 3rd party planning system that does terrain avoidance routing. I do not know yet what format their system needs the terrain data in, but I was hoping somebody could point me to the original terrain data location that was used to create the terrain models for Flight Gear. Hopefully there will be an easy way to convert between the two so the terrain in my FG demonstration will match up with where their planner things hills and water and such are. Second, while investigating some stuff for another project, I ran across a reference where somebody used a MS Flight Sim aircraft model for a Predator UAV and used it on Flight Gear. Unfortunately, it didn't explain how they did it. How would I go about doing this (since my project is to control a UAV, it would be a lot more credible to show the customer a Predator on the screen than a Piper Cub!)

[Flightgear-devel] Autopilot questions
Hey gang, I'm starting to prepare to integrate Flight Gear as a surrogate for a real UAV as part of a UAV control system that I'm developing. We've looked at several other simulators, but FG seems to be the best one for the job at hand. I do have several questions though about the autopilot system that I was hoping somebody could answer. Specifically, it seems (through my experimentation on 0.9.8) that some aircraft have more robust APs than others. For instance, the F-16 model shows on the display the next WP. Others don't show anything. Some seem to handle the WP following system, others don't. What we're specifically looking for is (at a minimum) a single engine (preferably prop, or better yet Helo in lieu of a real UAV model which nobody seems to have built yet for FG) aircraft model that can do a combination of altitude + speed holds, as well as auto fly from current location to a specific lat/long waypoint. There has been some discussion in my group as to the possible need to have a full flightplan (series of waypoints) that we could send to the sim to fly in order, but we don't think we need that at the current time. Instead we're probably going to do a fly to here, monitor the aircraft position, when we get there tell it to now fly to there, repeat... type control. We're doing our interfacing with FG through the Java telnet interface, so I'll need to know what parameters I need to modify to do each of those autopilot things. Any help is appreciated! --Mike Mike Kopack ISX Corporation 1800 Parkway Place Suite 900 Marietta, GA 30067 678-581-2025 [EMAIL PROTECTED] ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
[Flightgear-devel] Questions about IO system
Hey gang, I'm trying to write some Java code to interface with FlightGear's IO system via sockets. I'm running on Windows (don't know if that matters or not.) Anyhow, I need to do two things: 1) Have one socket sending flight commands (like changing the rudder position, or turning on/off the autopilot, setting throttle, etc.) These can come in at any time. 2) Have another socket that my code listens for periodic updates in status information from FlightGear (position, attitude, engine temp, fuel flow rates, etc.) From what I see in the documentation, it shows that you can do this. I'm a bit confused by it though. To do task #1 above, do I just open a socket to Flightgear on the specified port, then send a XML doc with just the 1 command element I want to specify? To do task #2 above, as I understand it, I have to set up a XML file on the machine running FG that basically tells FG what data I want sent back over the socket. Does it come across the wire as an XML doc every x.x seconds (I see that there's a Hz setting when specifying the socket connection in FG), or does it come across as comma delimited or something like that? Any help with this is greatly appreciated.

[Flightgear-devel] Any UAV models?
Does anyone know of any aircraft models for any UAV's? I don't really care if it's a fixed wing or a rotary aircraft, but I'd like to find something like a Predator or an X-35 UCAV or GLobal Hawk or Hunter or somethign along those lines. I really don't need much of a cockpit (if any), just a visual model and airframe and flight model. Anyone know of any sources? --Mike Mike Kopack ISX Corporation 1800 Parkway Place Suite 900 Marietta, GA 30067 678-581-2025 [EMAIL PROTECTED] ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
