The more that our society relies on GPS signals, the more important it is to safeguard them. But unfortunately, there is no backup in place.
Fortunately, the solution for this problem exists – Satellite Time and Location (STL) signals. STL signals provide the safest, strongest, most dependable backup to our GPS infrastructure. They originate from Iridium satellites, whose beams are high-powered, location-specific, and incredibly difficult to jam.
The energy grid, data networks, financial exchanges and military operations all depend on GPS. STL signals can protect them unlike any other, with cryptographic security features that are much more difficult to misdirect or “spoof.” Welcome to the evolution of Satellite Time and Location. Only from Satelles.
Military & Defense
US Military operations require unimpeded access to trusted Positioning, Navigation, and Timing (PNT) information for many applications such as asset navigation (ground troops/soldiers, ground vehicles, aerial vehicle, maritime vehicles, and more). Existing PNT relies on GPS signals and these signals can be limited or denied by terrain conditions or enemy interference such as spoofing or jamming. If a military asset loses the GPS satellite signal, PNT data can be lost and the asset no longer has the ability to recognize location and timing, meaning situational awareness has been compromised and the mission is threatened. Military assets increasingly operate in conditions that hinder or block access to GPS signals and it is imperative to provide trusted PNT information through other means.
Satellite Time and Location (STL) complements PNT service, when GPS signals are denied or intermittently available, and provides trusted and assured positioning, navigation, and timing for successful mission accomplishment. STL is a psuedolite and leverages the stronger Iridium signal thereby enhancing the assets’s ability to operate in a GPS-challenged environment. STL can operate in both mounted and dismounted conditions, across multiple platforms, and penetrate indoor environments. Additionally, STL’s high power signal structure is highly secure and resistant to spoofing as overlapping spot beams provide location-specific data that changes every few seconds. Satelles offers commercial off-the-shelf (COTS) technology applicable for DoD and other U.S. Government customers
Communication networks around the world rely on accurate timing and synchronization from GPS (or GNSS) signals to function properly. The loss of GPS (via spoofing, jamming, equipment failure, or spacecraft anomaly) has been know to disable critical equipment, including macrocells, distributed antenna system (DAS) installations, and small cells. LTE networks are particularly vulnerable to timing anomalies, and often have timing requirements of 1 microsecond or better. Single-tower timing errors outside of this range have the potential to disrupt communications over a broad local region, and a widespread outage of GPS could potentially render communications inoperable over entire nations.
Satellite Time and Location (STL), powered by Satelles, provides a completely independent backup or complement to GPS. The STL solution is global in reach, and is available today. STL provides trusted timing and synchronization for continued communications viability. STL’s high power signal structure is highly secure and resistant to spoofing as overlapping spot beams provide location-specific data that changes every few seconds.
For DAS and other in-building wireless installations, STL offers the added advantage of timing signals that penetrate into most buildings - including buildings with Low-E windows or metal and concrete siding and roofing. This means that in-building wireless installations that leverage STL can maintain synchronous timing without the need for an external GPS antenna. This is especially important for buildings in which securing roof rights, landlord permissions, or local zoning restrictions are a challenge. An indoor solution is also much less costly and risky to install and maintain.
Timestamps are critical in many data network environments. Regulatory requirements are driving US financial markets to adopt highly precise timestamps on incoming information and transactions, to ensure transparency and prevent fraud. When milliseconds are worth millions, as in high-frequency trading, high-precision time synchronization is vitally important. High-precision time synchronization service is particularly important in high-frequency trading, when milliseconds are worth millions. Traders using timing feed systems based on GPS could be exposed to GPS spoofing risks with disastrous financials outcomes and market failures. It is critical to safeguard the integrity of time stamps is to track multiple reference time sources, so that the clock can be continuously cross checked against other clocks. Satellite Time and Location (STL) serves as a backup for GPS timing and synchronization for financial and other data networks. If GPS signals are spoofed or jammed, STL provides trusted timing and synchronization for continued communications viability. STL’s high power signal structure is it highly secure and resistant to spoofing as overlapping spot beams provide location-specific data that changes every few seconds.
The US Utility Grid is becoming more vulnerable to hacking attacks as grid operators expand the use phase synchronization (synchrophasor systems) that rely on GPS signals for timing. These synchrophasor Systems utilize Phasor Measurement Units (PMUs) for providing electrical power system reliability and grid efficiency, synchronizing services among power networks, and finding malfunctions within transmission networks. PMUs rely on GPS to time-stamp their measurements, which are sent back to a central monitoring station for processing. GPS jamming or spoofing could manipulates a PMU’s time stamps, thereby causing a PMU to deliver erroneous measurements regarding power frequency reading/ power flow calculations, thereby causing overheating to some elements, overloaded lines or overloaded transformers, potentially causing blackouts or damage to power-grid equipment. Satellite Time and Location (STL) serves as a backup for GPS timing and synchronization for utility grid applications. If GPS signals are spoofed or jammed, STL provides trusted timing and synchronization for continued reliable synchrophaser operation. STL’s high power signal structure is it highly secure and resistant to spoofing as overlapping spot beams provide location-specific data that changes every few seconds. STL is compatible with PTP IEEE-1588 standards.
