Hello

I have been looking all over the place and have been unable to find the exact altitude of your launch site.
Could someone help me out? Also if anyone knows the average atmospheric pressure that would be very helpful.

Thank you

I figure about 5,500′ MSL for the North Site and 4,800′ MSL for the Atlas site. Can’t help you on the average barometric pressure…

I’ve always used about 5300 for both. I’ll have to haul the GPS out next launch and get some numbers.

I used topo maps… actually a lot more accurate (typically) than the altitude component of GPS.

I was truly surprised to see the N site at 5,500′. It is definitely higher than Atlas. I can dig out the topos sometime again, but 5,500′ and 4,800′ are quite close IIRC.

Yeah – the GPS would only be an estimate (accurate to 20 or 30 feet).

My GPS repeatedly reports 5430′ at the Pawneee North Site.

Thanks Guys

Within 20-30 ft is fine it is just for simulations, so it really is pretty close to a mile high.
All the weather sites show a pressure of 30 something inches of mercury. I’m a little skeptical.

I remember hearing 29.92 inches last oktoberfest. Not sure how representative that is though…

Atmospheric pressure will vary greatly day to day and over time. I don’t know that anywhere on earth that has any particular “average” atmospheric pressure.

I’m assuming this info was for simulation purposes? I use Rocksim V4.0, which has no way to set atmospheric pressure. RH (relative humidity) yes, but atmospheric pressure, no…

My GPS logged in 8810 from a road nearby the Hartsel site, which is pegged as 8820. DEAD accurate beyond any altimeter readings, will check both North and atlas now that i know the tech works(from an open range to 4 or more sats, mtn climbers take your baro units.)

We are Good to Go with our scheduled and approved launch on Saturday April 5th and Sunday April 6th, from the North Site, subject to change – Mostly cloudy and High Winds predicted. Range and waiver should be active by 9AM on Saturday. The Pawnee National Grassland remains fragile and dry, so extra precautions are in order. Please stay on the authorized roads and please don’t park more than 100’ off the road at the flight line.
