Gestionale per Aeroclub

Gestione Aeroclub:

Una web application completamente integrata per aeroclub, scuole di volo.

Fruibile da qualsiasi postazione connessa alla rete internet senza richiedere particolari requisiti hardware utilizzando un semplice browser web.

Gestionale per la registrazione dei voli con associato pilota, aeromobile, un aeroporto di partenza, uno di arrivo.

Possibilità di stampare stralci voli e conto voli, sia da parte della segreteria del club che dei soci, con accesso internet tramite web e diverse autorizzazioni e livelli di accesso.

Il software è in grado di effettuare la contabilità delle ore volo dei velivoli, tenendo conto delle scadenze ed ispezioni periodiche.

Ogni socio o allievo viene registrato in un'anagrafica che consente di associare uno o più livelli di accesso e diritti all'interno dell'applicativo, in modo da avere un accesso con un interfaccia personalizzata.

Nel caso di un Aeroclub viene effettuata anche la gestione dello scadenziario del pagamento delle quote associative, scadenziario visite mediche, scadenziario licenze ed abilitazioni.

Il software è completamente basato su tecnologie web ampiamente disponibili ed open source, come PHP, Mysql, PostgresSQL che permettono l'utilizzo di server Linux o servizi di Hosting con costi alla portata di qualsiasi Aeroclub.

A differenza di altri software similari:
L'applicazione non viene fornita in Cloud, non si deve pagare una fee annuale.
Si interagisce direttamente con lo sviluppatore che prepara l'applicazione per le specifiche esigenze
Predisposta per gestire Club che svolgono attività di volo a vela

First IOT attempt

This is my first IOT Internet of Things attempt, based on a Arduino YUN.
Is located in my Shack and connected to a 10 Watts solar panel, with two 7Ah PBgel Batteries in parallel.

Update of 2017:

Now the system is based on a Raspberry PI B+ connected to internet that sends tu Things Speak and the Hamradio APRS Network

thd7gps arduino firmware for Kenwood THD7 to translate nmea 183.3 to nmea 183.2

thd7gps

Source code and project on github

https://github.com/in3aqk/thd7gps




This is a Arduino firmware able to convert NMEA 183.3 strings to NMEA 183.2. It's necessary to let the old Kenwood TH-D7 hamradio rtx with unmodified firmware to work with new Nmea GPS.

The TH-D7 uses two NMEA sentences out of the many sent by the GPS unit every second: the $GPGGA and the $GPRMC.
Early firmware version did not recognize the commas separating the various fields inside these sentences, using instead a fixed-length method that could lead to wrong data interpretation.

For Example:

NMEA 183.3 GPS sends:

$GPRMC,192944,V,3733.8310,N,01504.5017,E,20.0,270.8,081205,2.0,E,S23 $GPGGA,192958,3733.8070,N,01504.4222,E,8,09,2.0,335.4,M,38.3,M,,4A

NMEA 183.2 GPS sends:

$GPRMC,192944,V,3733.831,N,01504.501,E,20.0,270.8,081205,2.0,E,S23 $GPGGA,192958,3733.807,N,01504.422,E,8,09,2.0,335.4,M,38.3,M,,4A

Pay attention the checksum on these examble string are probably wrong.

The 4 decimal digits in the Lat and Long fields instead of the 3 expected by the TH-D7 are the source of the incompatibility. The arduino code strips the extra digit and resent it to the TH-D7 in NMEA 183.2 format

The hardware in base on

• Arduino nano
• GPS whit nmea output
• Max 232 level converter

Hardware and firmware is able to:

• receive the NMEA strings with a software serial port
• identify the $GPGGA and $GPRMC sentences
• remove the least significant decimal digits exceeding the 3 expected by the radio
• recalculate the checksum
• transmit the nmea string to the radio with a software serial port

My first APRS Packet on ISS

Today I've sent and repeated my first APRS Packet through the International Space Station ISS.

The aprs path was ARISS.
Equipment:

TH-D7  many years old
Wimo sota Log Periodic Antenna
Power about 3 watt


During the pass I've "READ" a lot of other stations from all over Europe.
Being from Suedtirol, Dolomity Mountains, my message was Italy Dolomiti.

So the belove screenshot is like a qsl for me.
You can seen on the balloon that i was repeated by RS0ISS :

IN3AQK-246 antenna 144 Mhz, 70Mhz, 50Mhz multifunction sota - Field Radio Dipole

On my mountain activations I normally need a lightweight hamradio equipment.
The problem is that I'm not an athlete and doing a climb of 800 to 1000 meters, in Dolomiti mountains, above 2000 meters is not simple if you are not fit.

I do both HF and VHF activations but I prefer to use the altitude to try VHF and above qso.

I need a simple and re-configurable antenna able to work on 2 meters, 4 meters and 6 meters with a minimum effort, an antenna that could be used in vertical, horizontal polarization, in linear or inverted V configuration.

As you know the dipole a nearly no gain but it's surely better than the standard whip of a yaesu 817

I decided to built a strange dipole based on two 1,4 meters telescopic whips.
The dipole could be used atop a fiberglass rod.

The name is IN3AQK-246  ... the numbers are the bands :-)

Some photos are better than 1000 words

Antenna parameters at 50.100

Front view, the ferrite beads are used as a RF cocke

Really simple!!

Two new test instruments in my shack

Two new test instruments are now ready on my shack:

I've built them from a kit of components.

• IZ1PMX VNA vector network analyzer  from 2 Mhz to 180Mhz
• Multifunction tester, very cheap.

IZ1PMX  Vna

Is a Vector Network Analyzer, based on a projetc of Alfredo IZ1PMX

It's based on a Atmel Processor ATmega  and a AD9951 DDS.

The instrument has a frequency range from 2Mhz to 180Mhz but test has been done to 250 Mhz.

It's a really cheap kit, has a good price to performace ratio

The reference site is:

http://www.qrpitalia.it/

Here you could find also a QRP HF transceiver

IZ1PMX VNA 2-180 mhz

Multifunction Tester

I needed an Electrolytic ESR meter so searching on internet ad blogs I found this little an very very cheap instrument base on an Atmel atMega processor.

The funny is that this instrument reads completely automatically also:

• Capacity
• Inductance
• Resistance
• Electrolytic ESR

Detect and give information's about:

• Diodes
• Transistors
• Fet 
• Mosfet
• Tirystors

It's a really useful instrument especially when a component has to be tested or it's of unknown type.

The gear is electrically simple, all the operations are done by the microcontroller and the software.

It can be found on some online cinese shops.
