Nexus Observatory Inc. keeps a record of each choice as proof: a random consent ID, the time, your region and the rules applied, the choices, the notice shown, the page, a shortened IP address, a one-way code of your browser type and, if you are signed in, your account. Records are kept while your choice applies and for 3 years after, then deleted.Nexus Observatory Inc. conserve un registre de chaque choix à titre de preuve : un identifiant de consentement aléatoire, l'heure, votre région et les règles appliquées, les choix, l'avis affiché, la page, une adresse IP abrégée, un code à sens unique du type de navigateur et, si vous êtes connecté, votre compte. Les registres sont conservés tant que votre choix s'applique et pendant 3 ans par la suite, puis supprimés.

Academy
Learning paths, from what an observation is to a commissioned site: instruments and siting, links and clocks, edge compute and field AI, Earth observation, site operations, the open protocol, and the standards that make data trusted. Every lesson runs on the same atlas, spectrum and methods as the rest of this site.

START
01 · Principles
Source before claim, method before tool, evidence before sign-off. The rules the long-lived observatories in the atlas kept are the rules every lesson keeps.
01From the recordEach path opens with the observatories that met its problem, and the lesson they left, cited from the atlas.
02Method, then toolEvery calculation ships with its formula and a worked example you check by hand before any software runs it.
03Real dataExercises run on real elevation, real open networks and real standards, with their licences stated.
04Evidence, not badgesA module ends in an artefact someone else can check: a site plan, a link budget, a WIGOS record, a conformance run.
02 · Paths
Start anywhere. Paths cross where the work does: a site plan needs power, timing and backhaul, and every path ends on the protocol.
FoundationConcepts and vocabulary, no prerequisites.
PractitionerPlan, configure and check real systems.
AdvancedDesign, integrate and operate at scale.
01 · Path
Before the instrument, the idea: what an observation is, why it must be comparable, and how five thousand years of observatories learned to share units, hours and records.
For · Everyone: students, hosts, communities, new team members.
03 · How it works
The academy sits on the open main site. Read any lesson without signing in; an account keeps your progress, plans and runs. Teams work a path together in the NXS Observatory app.
