Studio: Pre-Configured Assets
Pre-configured Spacecraft, Vessels and Ground Stations exist in the Inventory panel of Nominal Studio. Each pre-configured digital twin is designed to assist Nominal Studio users in assembling simulations in a fast and concise manner. Each of the pre-configured assets can also be modified with additional components once included in a simulation. An example of the pre-configured spacecraft in inventory is shown below.
ISS (ZARYA)
The International Space Station (ISS) CelesTrak shown below is a preconfigured spacecraft with the mesh of the International Space Station. Via Nominal’s CelesTrak Integration, a request for the current TLE data is made before placing the ISS into a Nominal Studio Simulation.
Note
Nominal Studio will become momentarily unresponsive whilst actioning the CelesTrak Query. This also requires an active Internet connection to work and pull the data.
Warning
As the ISS CelesTrak Spacecraft doesn’t override the epoch of the simulation to match the epoch of the received TLE, it will spawn in the incorrect position along its orbit.
Mars Reconnaissance Orbiter
The Mars Reconnaissance Orbiter digital twin is preconfigured with dual solar panels, reaction wheels, a computer and a camera. At the spacecraft level, the digital twin is preconfigured with events to target its optical payload at Mars, the Earth and Saturn.
Landsat 8
The Landsat 8 digital twin is one of the more advanced preconfigured spacecraft provided, as it’s equipped with flight software to manage its operational state and an EPS simulation. The flight software will orientate the spacecraft into the NADIR (Earth orientation) pointing and will only activate the imaging payloads based on the following conditions:
- If the spacecraft isn’t in
Recharge Mode, as defined by the battery charge fraction trigger and recharged thresholds. - If the spacecraft isn’t eclipsed by its primary body
- If NADIR Pointing is within a suitable tolerance and has aligned the camera towards the ground
Whilst the payloads are active, they apply a load to the EPS simulation also present on the spacecraft. The spacecraft features events to manually capture or export the current images from the camera payloads, as well as opening a child window to display live feeds from both imaging payloads.
6U CubeSat
A generic 6U cube stat that features two deployable 6U solar panels via gimbals on either side of the spacecraft. On the underside of each deployable panel is a smaller solar panel. Present at the top of the spacecraft is an RF transmitter and receiver combo, with a RADAR payload at the bottom. The satellite internals include an IMU, electromagnetic sensor, battery, computer and reaction wheels. The spacecraft comes pre-configured with events to deploy and retract the gimballed solar panels and enable or disable the RADAR payload. An Event to visualize the RADAR Depth data is also available on the RADAR Payload.
3U CubeSat
A 3U CubeSat skewed towards electrical power systems (EPS) simulation, the spacecraft features two gimbaled deployable 3U solar panels, two batteries, four magnetorquers and three reaction wheels, as well as a computer and camera. As this spacecraft focuses on EPS simulation, it comes with events to enable or disable an EPS Fault condition on the deployable solar panels, as well as a battery leakage and an efficiency degradation on the central solar panel. Events to deploy and retract the gimballed solar panels are also included.
3U Heading Estimation CubeSat
A 3U CubeSat equipped with Course Sun Sensors and an EPS simulation. Designed to achieve Sun Pointing to charge its battery via the solar panel, the spacecraft also demonstrates which of its Course Sun Sensors have detected the Sun.
1U CubeSat
Skewed as a tech demonstrator cube sat for a novel thruster design, it features a thruster and internal fuel tank and is covered with 1U solar panels. Also included is a set of reaction wheels, a transmitter, a receiver, a computer and a battery. The events on this spacecraft include a one-second fire request for the thruster that will occur after a one-second delay and events to toggle a fuel blockage.
Lunar GNSS Lander
A simple digital twin of the Apollo Lander, this spacecraft includes a computer and GPS sensor for position determination simulations.
Hubble Space Telescope
The Hubble Space Telescope pre-configured spacecraft is designed for long-distance optical observation situations and includes a gimbled aperture door and solar panels in conjunction too a battery and computer. Actionable events exist to open and close the aperture door and to unfold the solar panels for the depicted state.
Ground Station Complex
Designed as a simple Ground Station, the pre-configured Ground Station complex is equipped with a radio-frequency transmitter and receiver. These communication systems enable it to communicate with spacecraft running on the same frequency.
Ground Station Dish
This pre-configured Ground Station is equipped with a radio-frequency receiver as well as a laser receiver. These communication systems enable it to receive communications from spacecraft in orbit.
Container Ship
A Container Ships is provided under the Vessel tab of the preconfigured inventory. The Ship can be configured to have a Receiver and Transmitter with the intent of being a observable target for space based assets.
