Secure satellite telecommunications connect people, infrastructure and essential services across distance—protecting the confidentiality, integrity and availability of information, including when terrestrial networks are disrupted.
PULSE assesses the signals, links and networks behind that mission: from RF quality and propagation to service continuity, resilience and authorised security telemetry.
Assess space, ground and user segments together. A strong RF link supports reliable service; security also depends on encryption, authentication, key management and the wider network architecture.
Emergency response, public authorities and essential infrastructure.
Maritime, aviation and remote land operations.
Enterprise connectivity, remote sites and network extension.
Path diversity, recovery, continuity and service-level monitoring.
Explore representative satellite networks and secure-connectivity programmes. The analytical approach is tailored to each system, accessible dataset and authorised test environment.
Eutelsat OneWeb · Starlink
Study satellite visibility, Doppler, terminal tracking, handover continuity and end-to-end quality of service. Performance depends on gateways, routing, traffic and terminal configuration.
Ku / Ka links · Mobility · Handover
SES O3b · O3b mPOWER
Assess beam resources, link budgets, gateway diversity, latency and delivered capacity across non-geostationary broadband services.
Link budgets · Capacity · Routing
Eutelsat GEO · SES GEO · Viasat / Inmarsat
Analyse wide-area or spot-beam coverage, propagation losses, interference, service availability and rain-fade mitigation. Frequency bands and capabilities vary by satellite and service.
Beam coverage · Propagation · Availability
Iridium · Globalstar
Evaluate mobile and IoT communications, acquisition, link reliability, message delivery and coverage constraints. Service characteristics differ between voice, narrowband data and IoT.
Mobile terminals · L-band services · Delivery
EU GOVSATCOM · IRIS²
GOVSATCOM pools satellite communication capacity for authorised public users. IRIS² is a developing secure-connectivity constellation. Assess service resilience, path diversity and policy-controlled operations; evaluate security assurance through dedicated controls and validation.
Secure services · Multi-orbit resilience
Connect authorised RF captures, modem measurements, network probes and system context in a traceable performance-assessment workflow.
Read IQ samples, spectrum traces, modem counters, packet statistics, ephemerides, antenna patterns and propagation inputs. Align clocks, units and calibration metadata.
Estimate PSD, occupied bandwidth, carrier offset, Doppler, C/N0, Es/N0, EVM, symbol timing and error rates using the applicable waveform and receiver configuration.
Combine link budgets, propagation, coverage and network KPIs. Correlate rain fades, interference indicators, handovers, packet loss, latency and throughput.
Investigate anomalies, compare thresholds and produce reports, plots, files, event logs and alerts. Preserve configuration and provenance for repeatable assessments.
DVB-S2/S2X and 3GPP NTN assessments use the applicable profile, test conditions and reference receiver.
Analytical views for telecommunications performance, troubleshooting and service assurance—from a captured waveform to a resilient end-to-end connection.
Measure occupied bandwidth, spectral shape, out-of-band emissions and adjacent-channel interference indicators. Retain sample rate, resolution bandwidth and calibration.
Assess EVM, phase noise, amplitude imbalance and residual carrier errors. The 16-QAM example is generic, not an operator waveform.
Compare error statistics against an appropriate analytical or simulated reference. This view shows uncoded coherent BPSK/QPSK in AWGN; coded MODCODs require their own curves.
Study predicted frequency offsets and tracking residuals across a LEO pass. Include ephemeris quality, oscillator stability and terminal dynamics.
Combine EIRP, receiver G/T, losses and propagation to assess margin and fade sensitivity. Evaluate the selected waveform and target availability.
Explore spatial link-margin variation for an idealised beam. This schematic is not an operator service-coverage map.
Track delay distributions, handover events and service interruptions. State round-trip or one-way measurement conventions and clock assumptions.
Compare offered traffic with delivered application data rate. Correlate contention, link adaptation and packet loss with service-level targets.
Measure outage duration, path recovery time and service continuity under authorised failure scenarios. Combine network evidence with approved security-event telemetry.
PULSE figures · Modelled scenarios. Select a figure to enlarge.
Relate measurements to calibrated equipment, documented waveforms and defined service targets. Expand each assessment layer.
Use calibrated power and spectrum measurements, known reference signals and receiver metadata. Record bandwidth definitions, frequency accuracy, time reference and measurement uncertainty.
Apply suitable ITU-R methods for atmospheric attenuation, rain fading and interference studies. Record frequency band, elevation, site location, climate inputs, polarisation and antenna patterns.
Use DVB-S2/S2X or applicable 3GPP NTN profiles where relevant. Distinguish symbol rate, occupied bandwidth, coding, roll-off and MODCOD. Operator-specific waveforms need their own authorised references.
Correlate authorised authentication, tunnel status, configuration, key-lifecycle events and network logs with availability and failover results. RF performance alone does not establish confidentiality, integrity or security certification.
