Ellipse-N High-performance RTK Inertial Navigation System

---

Inertial Navigation Systems from our company accept inputs from external aiding sensors, such as air data sensors, magnetometers, Odometers, DVL and other.

This integration makes the INS highly versatile and reliable, especially in GNSS-denied environments.

These external sensors enhance the overall performance and accuracy of the INS by providing complementary data.

Jamming and spoofing are two types of interference that can significantly affect the reliability and accuracy of satellite-based navigation systems like GNSS.

Jamming refers to the intentional disruption of satellite signals by broadcasting interfering signals on the same frequencies used by GNSS systems. This interference can overwhelm or drown out the legitimate satellite signals, rendering GNSS receivers unable to process the information accurately. Jamming is commonly used in military operations to disrupt the navigation capabilities of adversaries, and it can also affect civilian systems, leading to navigation failures and operational challenges.

Spoofing, on the other hand, involves the transmission of counterfeit signals that mimic genuine GNSS signals. These deceptive signals can mislead GNSS receivers into calculating incorrect positions or times. Spoofing can be used to misdirect or misinform navigation systems, potentially causing vehicles or aircraft to veer off course or providing false location data. Unlike jamming, which merely obstructs signal reception, spoofing actively deceives the receiver by presenting false information as legitimate.

Both jamming and spoofing pose significant threats to the integrity of GNSS-dependent systems, necessitating advanced countermeasures and resilient navigation technologies to ensure reliable operation in contested or challenging environments.

A Real Time Clock (RTC) is an electronic device designed to keep track of the current time and date, even when powered off. Widely utilized in applications requiring precise timekeeping, RTCs serve several key functions.

First, they maintain an accurate count of seconds, minutes, hours, days, months, and years, often incorporating leap year and day-of-week calculations for long-term precision. RTCs operate on low power and can run on battery backup, enabling them to continue keeping time during outages. They also provide timestamps for data entries and logs, ensuring accurate documentation.

Additionally, RTCs can trigger scheduled operations, allowing systems to wake up from low-power states or perform tasks at specified times. They play a crucial role in synchronizing multiple devices, ensuring they operate cohesively.

RTCs are integral in various devices, from computers and industrial equipment to IoT devices, enhancing functionality and ensuring reliable time management across multiple applications.

GNSS stands for Global Navigation Satellite System and GPS for Global Positioning System. These terms are often used interchangeably, but they refer to different concepts within satellite-based navigation systems.

GNSS is a collective term for all satellite navigation systems, while GPS refers specifically to the U.S. system. It includes multiple systems that provide more comprehensive global coverage, while GPS is just one of those systems.

You get improved accuracy and reliability with GNSS, by integrating data from multiple systems, whereas GPS alone might have limitations depending on satellite availability and environmental conditions.

GNSS represents the broader category of satellite navigation systems, including GPS and other systems, while GPS is a specific GNSS developed by the United States.
