Whoastra Labs · Survey Tools
Free tools for the subsea survey desk. Nothing to install, nothing leaves your machine.
Five self-contained browser tools for the jobs every survey office does — the USBL spin test, the sound velocity profile, the gyro calibration, the sensor offset drawings — plus the free desktop and phone software from Whoastra Labs. Each browser tool is one file: open it, use it, and save the page with Ctrl+S, or save all five at once with the button below, to keep a copy that works offline on the vessel.
Browser tools · offline ready
Open it, drop the file in, print the sheet.
No sign-up, no account, no internet needed once the page is open. Everything runs in your browser; “Save As” in each tool embeds the data in the saved file so a job can be picked up again later.
USBL Spin Test
Acoustic positioning offset spin check. Drop a survey export, auto-map columns, compute raw and edited means, DRMS / 2DRMS, tolerance rings, scatter and drift charts.
Launch tool →CTD SVP Builder
Parse a Sea-Bird .cnv (or .hex), build the sound-velocity profile report, and export APOS .usr and Fusion .pro files. Con-file serial cross-check, optional re-binning, comparison overlay, T/S QC chart.
Launch tool →ROV Gyro Calibration
Compute the compass offset (C-O) from vessel and ROV heading logs with LARS frame dimensions. Five moon-pool arrangements, close-up ROV diagram. Save As embeds all data.
Launch tool →ROV Sensor Offset Diagram
Enter survey sensor offsets from the vehicle CRP and draw a three-view (plan, profile, front) offset diagram sheet with numbered callouts, offset table, notes and a title block. Save As embeds all inputs; Export prints a landscape Letter sheet.
Launch tool →Vessel Sensor Offset Diagram
Enter vessel sensor offsets from the CRP and draw a plan-view offset diagram with named callouts, hull outline, helideck and anchored deck features (moonpool, crane, LARS), plus offset table and title block. Save As embeds all inputs; Export prints a portrait Letter sheet.
Launch tool →Desktop software
Small Windows programs for the survey office.
Standalone executables, no install for most of them; source on GitHub where the card says so. WoodTerm and WoodVNC are part of WoodSolutions and have their own pages.
WoodTerm
Cross-platform serial + network terminal for offshore survey device testing. Serial, TCP, UDP (multicast / broadcast), NMEA validation, logging, a serial-to-UDP repeater and a protocol simulator.
Product page →WoodCopy
Directory synchronisation for the Whoastra suite. Mirror, copy and two-way sync with per-pair filters, schedules and SFTP remotes. SHA-256 verification, dry-run previews, versioned trash bin, headless CLI. Standalone Windows .exe, no install.
GitHub →WoodPDF
Offline PDF editor for Windows: view, annotate, edit text and images, fill forms, sign and run OCR. Merge, split, rotate and reorder pages, redact, watermark and compare documents. AES-256 encryption. Standalone Windows .exe, no install.
GitHub →HeloMon
Live offshore helideck motion monitor. Reads vessel pitch / roll / heave over UDP and shows a big GREEN / AMBER / RED deck status with a stabilising landable countdown and three scrolling time series. Configurable limits. Reference only, not a credited HMS.
GitHub →WoodVNC
Self-hosted, browser-based remote desktop for a private network. Every computer runs the same installer and every dashboard lists all the others: no central server, no port forwarding, no per-machine setup. Optional dashboard password, per-machine approval, audit log.
Product page →Phone apps
The same tools in your pocket.
Android APKs: download on the phone, allow the install from your browser, done. Both work offline.
WoodTerm · Android
WoodTerm for Android: serial (USB OTG) and network terminal for offshore survey device testing on phones and tablets. TCP, UDP (multicast / broadcast), NMEA validation, logging, dark theme.
Download APK →WoodOffset · Android
The ROV and Vessel Sensor Offset Diagram tools as a phone app, for measuring off the vehicle without a notepad. Pick a sensor, type the tape value and tap PORT / STBD, FWD / AFT, UP / DOWN; the point appears live on the diagram. Makes the PDF drawing sheet straight to Downloads and can hand it back to the browser tools fully editable. Works offline.
