Radiosonde AS-16
End-to-end encrypted radiosonde with integrated ground station software. From balloon launch to GTS message delivery in one seamless platform.
System Overview
The Aaizel AS-16 System is a fully integrated upper-air sounding solution combining the AS-16 encrypted GNSS radiosonde with the GS-16 ground station platform and production-grade processing software.
AS-16 Sonde
PTU + GNSS + AES
GS-17 Receiver
Dual CC1120 + AFC
Processing
QC + Derived Params
Encoding
WMO + STANAG
Delivery
GTS / SFTP / MQTT
Why a Complete System?
Seamless integration eliminates complexity and ensures reliable operations.
End-to-End Encryption
AES-128-CTR from sonde transmitter to ground station decryption. Per-unit cryptographic keys via HSM. Data never in clear text over RF link.
Zero Manual Steps
Automated pipeline: frame reception → QC → standard levels → message generation → GTS upload. Operator launches balloon; system handles the rest.
14 Message Formats
WMO: TTAA/BB/CC/DD + PPAA/BB/CC/DD. NATO: METB2, METB3, METCM, METFM, METSR, METTA. All generated automatically.
Multi-GNSS Wind
GPS + GLONASS + Galileo + BeiDou + NAVIC Doppler velocity. Wind speed uncertainty <0.15 m/s, direction <2°. No COCOM altitude limits.
Processing runs at 1 Hz frame rate with <50ms per-frame latency. Seamlessly coupled with GS-16 hardware.
