The GoPro camera took a photo every 5 seconds and recorded video the entire duration of the flight. The video will be made available at a later date when I get time to do some editing. Aerial Photos -Rog
Very consistent track predictions all week. Track length is just over 100 miles southeast, with a landing south of Pawnee City, NE. Should be a cool day for a drive with highs in the low 60's. Cloud cover should be much less than predicted earlier this week.
There has been little change in the track prediction and the weather for Saturday's flight. It should be a cool morning, mostly cloudy, northwest wind around 10 mph, and temperature in the 40's with a slight chance of rain at launch time.
110 mile track to northeast Kansas
Brad and Allen from ARAN stopped by last night to drop off the APRS Pi-gate they built for use during Saturday's flight so I could run it through a few tests. Worked like a champ.
I've been a little scatter-brained with last minute preparations for the upcoming flight, but thought I should share a few details as I've had some folks inquiring.
The Central Nebraska Near Space Program along with Nebraska Stratospheric Amateur Radio will be launching two weather balloons Saturday, 14-May-2016 on behalf of the Edgerton Explorit Center in Aurora, NE. Launch Time: 9:15 - 9:30 AM CDT Location: East side of Edgerton Explorit Center Google Map Link of location
What kind of equipment will be in the payload containers?
(2) APRS trackers consisting of GPS, microprocessor, amateur radio transmitters operating on 144.390 MHz and 144.360 MHz
(2) GoPro cameras for in-flight recording of photos and video
(1) CW - Morse Code Beacon transmitting "KC0MWM Balloon" about once a minute on 146.565 MHz
(1) SSTV - Slow Scan Television transmitter on the Martin 1 mode at 443.450 MHz
In flight monitoring of temperature, relative humidity, and atmospheric pressure data will also be available on one of the APRS signals.
The balloons can be tracked online at the aprs.fi website using the following link once the balloons are airborne
The Hastings, NE amateur radio club ARAN (Amateur Radio Association of Nebraska) has completed assembly and testing of their Slow Scan Television or SSTV payload. SSTV is a method of sending still images using a narrow bandwidth. A single image will take about two minutes to transmit. The payload will be sending in-flight images to a ground station every four minutes, using the Martin 1 SSTV mode on 443.500 MHz.

Below are a couple of test images sent
Thanks Brad KD0JCP, Allen KB0ASQ, and any others that helped to design and build this payload as well as the APRS Igates that will be used the day of the launch.
We're just shy of a month away from my first launch in almost six years. I've been busy reworking, redesigning, and testing the payloads that will be used on the upcoming flight.
The launch is in support of the Edgerton Explorit Center, in Aurora, NE. Location: East side of the Edgerton Explorit Center Date: Saturday, May 14, 2016 Launch Time: 9:30 AM CDT
My friend and ARHAB mentor, Mark Conner N9XTN from NSTAR will also be launching a balloon that day. Here's a few images of what I've been working on:
Soft-sided lunch coolers make good payload containers. I started using these back in 2005, one of the many ideas I borrowed from Mark N9XTN.
APRS tracking circuitry consisting of a UniTraq model GT-320FW(AS) GPS module and an ArgentData OpenTracker+ SMT. This payload has been fairly reliable the past couple of flights.
Alinco DJ-S11 2 meter transceiver and battery pack tucked away in foam. Top of the image is the data logger enclosure and its GPS module (upper left).

Had to do a few repairs to the CW beacon.
The CW beacon has a new home, tucked inside the foam (pool noodle) on the GoPro camera payload.
Dual GoPro cameras for HD video and stills
I'm waiting for one more device to arrive. Apparently the USPS lost my newest gear somewhere in the Pacific Northwest, so a new one is being shipped and should arrive this week. I'll be trying out a Tracksoar. A new Open Source APRS tracking module. It was a KickStarter project that got funding earlier this year.
As we get closer to launch day I'll be updating this site with the latest information as well as my Twitter account. - Rog KC0MWM
Aside from adding some payload string tie points, the data logger payload is now complete for the upcoming launch. Data is logged every 5 seconds and includes time, latitude, longitude, speed, course, date, number of satellites in solution, horizontal dilution of position, altitude, internal temperature, external temperature, relative humidity, absolute atmospheric pressure, and power supply voltage. Special thanks to Roger Frandsen for checking my math on the A/D conversion, and correcting my error(s).
Working on a new payload for the upcoming balloon launch. Learning to parse GPS data strings on the PICAXE processor and add sensor data to be output to an in-flight data logger, so I don' t have to rely on the APRS telemetry.
I've been corresponding the past several months with Dan Glomski from Edgerton Explorit Center in Aurora, NE about doing a high altitude balloon launch as part of their Super Science Saturday program. Dan and I had a chance to sit down earlier this week and hammer out some of the details.

The old CNNSP website is terribly out of date and I didn't feel like learning yet another piece of web development software. I opted to save some money by doing away with my current web hosting space for that site and move nearly all of the contents over to Google's Blogger. At some time in the next few months before my hosting is up for renewal, I'll point my domain name www.cnnsp.org over to this blog, which is cnnsp.blogspot.com
For now this blog is the place to check for new information.
