On March 17, 1958, Vanguard 1 became the second artificial #satellite successfully placed in Earth orbit by USA. It was the first #picosatellite and the first with solar-powered. Just 6 in diameter and weighing just 1.4 kg, Vanguard 1 is the oldest satellite around the earth, was described by then-Soviet Premier as "The grapefruit satellite."

Six decades ago the state of the art allowed the concretion of this picosatellite, consider where and how far we can get with current technology.

Hi to All, It's a new year, and hopefully we have all recovered from the holidays.
We hope this year see the launch of #Arduiqube ,a #pocketqube satellite class, carrying university experiments and UHF #amateurradio   beacon. #hamr #cubesat  #amsat

TUBESAT and ISS Deployer.

The #tubesat is a #satellite design of interorbital for  launch  on rocket  Neptune of their property. There are two   #tubesat ready for launch, Ubatubesat (Bra) and Ulises-1(Mex).

The rocket is on  testing yet so  the Ubatubesat and Ulises-1 owners decided use a special deployer for launch from ISS. The deployer was designed by the people of #GAUSS and Morehead  University. In the pictures the deployer and a tubesat models as they are showed on Brasilia's   #Cubesat Workshop. #satellite

1st Latin America Cubesat Workshop Success!

A big success was the 1st Latin america #cubesat workshop 2014, organized by Brasilia university and International Academy of Astronautic.

More than 200 participants from around the world were met in the nice Brasilia city during four days to share their experience, projects and make new friends.

Our organization was present, showing our pocketqube project, ArduiQUBE.

Undoubtedly a great event and wait the new workshop in 2015.

Other #PocketQube Controller Flight on #Balloon

On November 9, 2014 at 14:35 UTC  was launched from the town of Longchamps,BA, Argentina a small balloon raising a payload (Austro-B), consisting in Arduino homemade plate , UHF transceiver and a GPS receiver, with a weight of 30 grams.

This is another test of the Arduiqube project, where we could  test the electronic in extreme conditions of temperature under -60 degrees and very low atmospheric pression.

The small balloon Kaysam 30g  elevated the light payload to 12 km altitude over the Rio de La Plata, where due the balloon's   two meters expantion broke and landed near the Uruguayan coast. The flight time was 90 minutes from  11:35 until 16:01 UTC, when contact was lost.

The next experience for end of January 2015. #arduino

Flight Review of the #Pocketqube controller payload in #balloon.

On Saturday August 30, 2014, at 17:43 UTC was launched successfully  Austro-Arduiqube balloon. The objetive was test the  design of a pocketqube controller.

The position of the base was located on the outskirts of the city of San Vicente, (- 35.049814,  -58.42875), participated  Daniel  (LU9DOG), Sebastian (LU2BFM) ,Flavio (LU2AVW) and Gustavo (LW2DTZ).
For the reception one 7el mounted yagi was used on a tripod 1.2 m above the ground, a TH-F6 receiver and a netbook.
 
The Kaysam balloon of  30 grams was inflated with 0.2 M3 enough helium to lift all the set of 120 grams.

The payload was turned on  and began transmitting data. The internet connection (in midfield), could not be established, so that decided to release the balloon and test the connection during flight.

Ascent speed was 153 m / min, half of the calculated. The surface winds from NE made that  the balloon did dirigiese further south than estimated by prediction programs.

Around 18:31 UTC, GPRS link was established and DL-FLdigi began sending  data to spacenear.us updating the position every 5 minutes. At this point the antenna was kept at zero degree elevation pointing south. One could observe the low temperature of the power amplifier permanently and RSSI level was lowered as the payload kept rising altitud.

The last position is valid at 19:06 UTC took 12,130 meters.At this time the balloon was less than 5 degrees of elevation and 92 km away from the base (-35.60869, -57.68901). From then on the GPS started send  longitude, latitude and height to zero.

The signal was barely audible but enough to continue decoding RTTY. The temperature of the PA was still down to 4 degrees centigrade , considering this,  the payload  followed up to 14 km in height.

At 19:35  stopped  the signal reception and experience was  terminated.

Since the #GPS could not resolve the position  the search is desisted.
Probably  insulation coverage was not enough for   GPS receiver and it has frozen but not for Arduino "fatto in casa", the transceiver and Li-Ion battery. The  Kaysam balloon  exceeded expectations of  flight time and altitud reach.
