Guides
Practical, iPhone-focused walkthroughs for flying Altus Metrum hardware with AltosUI. Every guide is scoped to what the iOS app actually does — launch day, recovery, and post-flight review.
Getting Started
AltosUI on iPhone: what it is (and what it isn’t)
A plain-language overview of what the iOS app does, what belongs to the desktop AltosUI workbench, and why the two share a name.
Pair your TeleBT v4 with AltosUI
First-time Bluetooth LE pairing, a frequency check, and the handful of fixes for “won’t connect” that cover almost every case.
Launch day on iPhone: unboxing to recovery
End-to-end walk: pre-flight on the Pad tab, ascent on the Flight tab, map tracking, and the walk to your rocket on Recover.
Flight Computer Guides
Flying TeleMetrum with AltosUI
What TeleMetrum (v1–v4) sends over the radio, what AltosUI shows in flight, and how recovery reads on iPhone.
Flying TeleMega with AltosUI
Six pyro channels, the 3-axis IMU, and separate pyro battery on TeleMega v1–v7 — how it all surfaces in the app.
Flying TeleMini with AltosUI
Small airframe tracking with TeleMini v2/v3 — honest about no GPS, no IMU, and what that means on the Flight and Recover tabs.
Tracking with TeleGPS and AltosUI
TeleGPS v1–v4 as a tracker-only device: the simplified flight-state machine and when this is the right tool.
Features & Workflows
Where AltosUI stores your .telem files
Files folder, Quick Look previews, copying to desktop, and the “empty telemetry folder” gotcha explained.
Pre-load offline maps before you leave Wi-Fi or cell coverage
Choosing zoom ranges, radius, and tile types — including the walking-recovery tiles you’ll want on foot.
The launch-site overlay catalog
What the worldwide site overlay shows, how to toggle per-site annotations, and how to request a field be added.
Voice callouts during flight
What AltosUI announces, when, and why the callouts wait for a valid GPS fix before speaking.
Walk to your rocket with AR and the Recovery Map
The Recover tab’s two guidance modes: which to reach for when, and what each shows you on the walk.
The GPS uncertainty circle — what the radius means
How HDOP drives the search area, what a large circle is telling you, and how to read it in AR versus the map.
On-device Flight Reports and PDF sharing
Generate a post-flight summary from a .telem file, export it as a paginated PDF, and share it with teammates or attach it to your flight log.
Replay any flight from a .telem file
Actual-time and fast playback through the full pipeline — a recorded flight driving every tab as if it were live.
Yagi + TeleBT + iPhone for range
Field practice for squeezing more range from a TeleBT v4 ground station without going out of scope.
