Space is no longer the exclusive domain of government agencies. A growing ecosystem of commercial launch providers, satellite data platforms, space situational awareness companies, and in-space services vendors now operate mission-critical software that must run continuously — often across ground stations on multiple continents, serving enterprise and government customers with exacting SLA requirements.
When your ground station management system goes down, a satellite pass may be missed. When your satellite imagery API fails, a downstream customer's analysis pipeline stalls. When your launch telemetry dashboard crashes during a critical window, your operations team is flying blind. Space Tech uptime is not a nice-to-have: it is operationally essential.
This guide covers the specific monitoring challenges facing Space Tech startups and how Vigilmon provides the external monitoring infrastructure your team needs.
The Monitoring Challenges Unique to Space Tech
Mission-Critical Windows
Space operations are inherently time-constrained. Satellite passes, launch windows, orbital insertion burns, and telemetry downlink windows are fixed in time. Software outages during these windows can cause mission degradation or total loss. Unlike a SaaS product where downtime means frustrated users, downtime during a critical pass window can mean lost data, a missed manoeuvre opportunity, or a communications blackout with an asset in orbit.
Global Ground Station Networks
Commercial space companies typically operate across multiple ground stations — in North America, Europe, the Southern Hemisphere, and beyond. Each station runs a mix of custom software, third-party scheduling tools, and cloud APIs. An outage at one location may not be visible from another, meaning failures can persist undetected until an operator notices manual symptoms.
Dual Customer Types
Space Tech companies serve both enterprise commercial customers (earth observation buyers, satellite connectivity subscribers) and government or defence customers (national space agencies, military contractors). Both segments have strict availability requirements. Government contracts often mandate documented uptime records and incident reports. Enterprise customers may invoke SLA credits after even brief outages.
Complex Integration Chains
Modern commercial space platforms integrate with cloud infrastructure (AWS Ground Station, Microsoft Azure Orbital), launch provider APIs, third-party telemetry pipelines, and customer-facing analytics dashboards. Each integration point is a potential failure node. A failure in one upstream API can cascade silently through a chain of dependent services.
What to Monitor in a Space Tech Platform
1. Ground Station Scheduling APIs
If customers or internal operators book ground station passes via an API, that endpoint is mission-critical. Monitor:
- Pass scheduling API (HTTP availability and response time)
- Authentication endpoints
- Conflict detection and booking confirmation webhooks
Check interval: every 1–2 minutes. Alert immediately on failure — pass windows are time-bounded.
2. Mission Control and Telemetry Dashboards
Operations teams depend on real-time telemetry dashboards. Even a few minutes of dashboard downtime during an active pass window disrupts situational awareness. Monitor:
- Dashboard login and authentication flows
- Real-time data feed endpoints
- WebSocket or streaming telemetry endpoints (via TCP checks on relevant ports)
3. Satellite Data and Imagery APIs
If your platform exposes satellite imagery, AIS data, or earth observation products via API, those endpoints are your customers' primary integration point. Monitor:
- Data catalogue and search endpoints
- Download and streaming delivery APIs
- Webhook callbacks that notify customers of new data availability
4. Customer-Facing Portals
Enterprise and government customers access tasking portals, data portals, and mission dashboards. Monitor:
- Portal homepage availability
- Login and SSO flows
- Report download endpoints
5. Background Job Heartbeats
Space platforms run time-critical background processes: telemetry ingestion jobs, orbital prediction computation, data processing pipelines, and billing reconciliation. A silent failure in any of these can cause cascading data gaps or missed alerts. For each critical job:
- Create a heartbeat monitor in Vigilmon
- Set the expected ping interval (e.g., every 5 minutes for a continuous telemetry ingestion process)
- Emit a heartbeat ping at the end of each successful run
If the job stops running, Vigilmon alerts your team before the gap becomes operationally significant.
6. TCP Port Monitoring for Ground Station Software
Many ground station systems expose custom TCP services for antenna control, spectrum management, or modem interfaces. Vigilmon's TCP monitoring can check that these ports are reachable and responding — catching network-level failures that HTTP checks won't surface.
7. SSL Certificate Health
Space platforms handle sensitive government and enterprise data over HTTPS. SSL certificate expiry is a preventable failure. Vigilmon monitors certificate validity and chain health, alerting weeks before expiry so your team can renew without incident.
How Vigilmon Addresses Space Tech Monitoring Needs
External Monitoring That Doesn't Depend on Your Infrastructure
Internal monitoring (CloudWatch, Prometheus, Grafana) goes dark when your infrastructure goes dark. Vigilmon checks your endpoints from external probe locations — so when your cloud region fails or your API gateway is misconfigured, you receive an alert from outside the affected zone. For Space Tech companies operating on thin engineering teams, external monitoring is the safety net that catches what internal tools miss.
Multi-Location Verification
Vigilmon verifies outages from multiple geographic probe locations before triggering an alert. This eliminates false positives caused by transient regional network blips — important for space operations teams who cannot afford alert fatigue during already-stressful operational windows. When Vigilmon alerts, you know it is a real outage affecting real users.
Response Time History
Space platform SLAs often include latency commitments in addition to availability. Vigilmon records response time history for every monitor, giving your team the data to detect performance degradation before it crosses the availability threshold. Period-over-period latency trends surface infrastructure problems early.
Status Pages for Government and Enterprise Customers
Government and enterprise space customers expect professional incident communication. Vigilmon's status page lets you publish real-time service status publicly or to a private audience, post incident updates in real time, and provide a documented record of availability for contract renewals and compliance reviews. Set up a branded status page at status.yourcompany.com with Vigilmon's custom domain feature.
Webhook-Based Alerting
Space Tech teams use a mix of communication tools — Slack for operations channels, PagerDuty for on-call escalation, custom incident management systems. Vigilmon's webhook alerts integrate with any HTTP endpoint, so your alerting fits your team's existing workflow.
Practical Setup for Space Tech Teams
Week 1 priorities:
- Monitor ground station scheduling API with 1-minute checks
- Monitor customer-facing data API and portal
- Set up heartbeat monitors for telemetry ingestion and data processing jobs
- Enable SSL monitoring for all public endpoints
Week 2 priorities:
- Configure multi-location verification for mission-critical endpoints
- Integrate Vigilmon webhook alerts with your ops Slack channel and PagerDuty
- Launch your status page for enterprise customers
Ongoing:
- Review response time history weekly during operational reviews
- Add TCP monitors for new ground station software deployments
- Export incident logs for SLA reporting and government contract compliance
Getting Started
Space Tech companies operate at the intersection of extreme technical complexity and extreme operational consequence. Your monitoring infrastructure should match that environment: external, reliable, fast to alert, and easy to report from.
