Dual temperature and humidity channels, barometric pressure, derived altitude and an air-quality index, sampled continuously through ascent and descent.
A balloon-borne instrumentation platform built by students to sound the lower atmosphere — pressure, temperature, humidity, air quality and attitude, streamed to the ground over LoRa and GSM in real time.
NIMBUS is an atmospheric monitoring initiative from The Space Association at BVM Engineering College. A single flight-ready unit carries the full sensor stack, an in-house flight computer and a redundant radio chain — cheap enough for a student team, rigorous enough to produce data worth analysing.
Every packet the vehicle has ever sent is archived and replayed through the mission control console on this site. Nothing here is a mockup.
Dual temperature and humidity channels, barometric pressure, derived altitude and an air-quality index, sampled continuously through ascent and descent.
LoRa carries telemetry tens of kilometres on milliwatts. A GSM path runs in parallel so a lost radio link never means lost data.
A 6-axis IMU logs roll and pitch alongside GPS, letting us rebuild the flight path and the vehicle's behaviour under the balloon.
Component selection, PCB layout, structural design, RF testing and recovery — all carried out by undergraduates, documented publicly in the mission logs.
The crew came together around a single question: how cheaply can a student team put a genuinely useful atmospheric instrument above the weather?
Microcontroller, sensor suite and radios selected for reliability per rupee, then bench-validated one subsystem at a time before anything was integrated.
Weeks of field testing on encoding, packet structure and antenna placement, ending in a full breadboard integration with every subsystem live at once.
The prototype collapsed onto a custom board — component placement, signal integrity and power distribution — while the chassis was modelled for thermal and aerodynamic behaviour.
Board bring-up, harness integration and end-to-end rehearsal of the telemetry chain from sensor to ground console.
Live sorties over Gujarat. The archived flight record on this site is replayed packet-by-packet through the mission control console.

Breadboard to flight article — component placement, signal integrity, thermal management and a chassis modelled for the ride up.

From vision to components: defining the mission, building the BOM and validating every sensor before integration.
Access data →A balloon climbing out of the troposphere with the payload slung beneath it, over the limb of an Earth the crew has only ever seen from the ground. The dashed ring is the flight track; the beacon on the payload is the downlink.

Birla Vishvakarma Mahavidyalaya provides the laboratories, instrumentation and faculty mentorship that make a flight-grade build possible on a student budget.
The console replays the archived flight record in real time — vitals, attitude, charts and the live ground track, exactly as the operators saw it.
