Lazy post… so that I don’t have to dig through the code, can anyone share roughly how the calcs are done for the max altitude reporting of the TeleMetrum on the AltosUI Flight Statistics tab (like the attached image from an EasyMini flight)? Does the GPS altitude get a heavier weight than the baro?
I’m thinking about buying a TeleMetrum for J & K record attempts next month. Since my launch location will likely be about 50 deg F above standard day, I’m expecting the pressure altitude to be 1000+ ft off from geometric altitude for the 26-33k AGL altitudes I’m hoping to hit. I know the baros have a temperature correction built in, but with the actual atmosphere much hotter than standard day plus the inside of my black rocket being extra warm I’m don’t expect much accuracy from the baro.
Can anyone tell me how to set up the Kenwood Th-D72 to receive the directional signals from the Telemini?
No problem connecting to Telemini, configuring or even firing igniters but can't figure out how to use my Kenwood to receive the signals.
Reviving this thread…
I’m starting my hacking to get the TeleMini v3 to read an external u-blox GPS. I’m doing serial port config stuff. It looks like I have to set a few things in ao_pins.h, but I’m not sure which serial 1 settings the TeleMini needs. I’m guessing PA9/PA10 is the right serial 1 setting. (Although AO_PA11_PA12_RMP is defined in the USB section.) Does this look right?
#define USE_SERIAL_1_STDIN 0
#define SERIAL_1_PB6_PB7 0
#define SERIAL_1_PA9_PA10 1
If it needs PA11 & 12, I don’t see those defined in ao_serial_stm.c. I’m guessing that would look like the PA9 & 10 chunk of code except with 11 & 12 (gpioa & STM_AFR_AF1). ?
Altus Metrum announces AltosUI for iOS
Our friends at Iron Sheep Productions, LLC have created the AltosUI
iOS application to bring Altus Metrum application support to Apple
iPhone and iPad devices. Available now in the Apple App Store, AltosUI
for iOS monitors your rocket flight through a TeleBT v4 ground
station, reporting status on the screen and through voice
synthesis. Once your rocket is on the ground, you can use AltosUI for
iOS to walk to your rocket with live maps. More details about AltosUI
for iOS are available here:
With the introduction of this new iOS application, Altus Metrum
products are the first rocketry products to include full support for
ground stations running the customer's choice of Windows, MacOS,
Linux, Android, or iOS.
