telemetry

Hi all, I’m working on a rocket that’s going to use an L-class motor and have gone with a phenolic tube (which will be wrapped in a fiberglass sleeve) for the airframe. I know the phenolic tube isn’t RF-transparent, but how do people using phenolic tubes usually perform any telemetry (if they...

Hey all, I'm trying to find more information about using the BMP390 for my rocket team's payload flight computer. The payload is basically a self-landing UAS. I am designing a 2x2in PCB to include a Teensy microcontroller communicating with a RFM95 LoRa telemetry radio, BNO055 IMU (using the...

My high school senior class is building a hybrid rocket to achieve and altitude of 50,000 ft. or 15,240 m. I am in charge of the payload and telemetry portion of the rocket and am a bit confused on what to do. The system must include barometric pressure, an accelerometer, GPS, and tank...

Hey Fellow Rocketry Geeks 🤓 I've recently joined this addiction and can't stop. I'm new to Rocketry but not new to electronics, programming and mechatronics. Rocketry allows me todo all of the above. I live in Canada and LPR is my only choice. But that should not be a limitation. As a result I...

Hello! I am in my university's Rocket Club and am trying to design our telemetry transmission system for our Avionics Team. We are building our own hybrid-engine rocket, and our first launch is expected to reach an apogee of approximately 500 meters. We want to send data from sensors...

Recently I ordered an Eggtimer Quark and the associated telemetry module as well as a USB Dongle receiver(also from eggtimer) I chose this receiver because the handheld receiver seemed a bit small for my needs and I would prefer that the data be sent to my laptop through the USB Reciever...

I admit my ignorance in terms of antennas and GPS/telemetry transmission range. This is an AIM XTRA 2.0. I added the two 90 degree elbows to fit my antenna into my av bay. Will the addition of the elbows increase transmission range, decrease range, or have a negligible impact on range?

Gheem on "The Rocketry Show" podcast #88 mentioned the AIM XTRA GPS/Telemetry/Altimeter package from "Off We Go Rocketry." Checking on their web site, I see only the 2.0 hardware version currently available for sale--but Gheem mentioned a newer 3.0 version that is now available. The Rocketry...

I'm not very familiar with the system but looks pretty basic. I've got a really good price for it, just not sure whether to pull the trigger or not. NE1 want to enlighten me? Thank you for your help!

Hi, I am wanting to transmit GPS coordinates and altitude from an Arduino onboard a model rocket that will go 1km high, to another Arduino on the ground. The purpose is just to assist in finding the rocket once it lands. I was needing something cheap but also not too large (about 3-4cm). I was...

We are working on a model rocket project, it will carry a scientific payload and it will be launched to 3 km altitude. We have a data link between the rocket and the ground station, we are using RFM96W pair now. However, we need to get data from the payload so our receiver should be able to...

We are, as a team, a competitor for model rocket competition. And we need to use two flight computers in the rocket and two ground control stations(GCS) for redundancy. We can design our custom computer and custom GCS, however, we can't predict the risks of using two telemetries together for...

Hi everyone! I'm newbie here, while I was researching about model rocket studies, I found this forum and signed up here :) Here are lots of information and I want to follow them always. However, I want you to guide me for our student project. We are a team which is a competitor for...

Hi! I'm a member of the UVic (University of Victoria) Rocketry team, and I'm trying to find a publicly accessible collection of flight data from a large number of amateur high-power rocket flights. I'm most interested in altitude, location, and/or acceleration data over time, but any sort of...

Version 2 of the APRS 2-Meter TrackSoar tracker has been introduced, and is available for pre-orders now. A great solution for rocketeers who not only want to track and recover their rockets, but also want to capture real-time telemetry during the flight. I've flown the original TrackSoar on...
