The GRAVMAX Negative Gravioli Detector is a scientific instrument and environmental sensor that measures the local gravity. It displays the acceleration on the craft due to gravity in meters per second squared (m/s²) when right clicked.

In career mode, it is available with Advanced Science Tech, at level 8 of the technology tree.

Product description

A device for capturing and measuring the elusive Negative Gravioli Particle, used for determining the precise strength of gravitational fields. Warranty void if used to detect Positive Gravioli Particles.

Usage

The GRAVMAX Negative Gravioli Detector can be radially mounted to a vessel. It is a physicsless part, and its mass and drag are instead added to its parent part.

Right-clicking on the GRAVMAX Negative Gravioli Detector (from the vessel or from a scientist on EVA) will reveal an option to "Log Gravity Data". Using this option will make the GRAVMAX perform a Gravity Scan, which can earn the player Science. A Gravity Scan appears to focus on deviations in the local gravity; experiment messages sometimes focus on fluctuations, such as a mass below the planet's surface increasing the strength of gravity.

A Gravity Scan can be performed while at rest on a celestial body's surface (landed or splashed), or while in space. A unique Gravity Scan can be taken from every biome, in all situations. A Gravity Scan cannot be performed while in flight in a body's atmosphere, or while sinking into a body's oceans. Note that "Landed" and "Splashed" are two separate scenarios; a GRAVMAX can perform two scans from a water biome, one while floating on the water, and one while sunk onto the ocean floor.

The GRAVMAX is the only scientific instrument with biome-specific results from space, and the only scientific experiment of any kind with biome-specific results from high space. Combined with its high science value, this makes the GRAVMAX a massive source of science points once unlocked. In order to take full advantage of this, it is best to send a probe with the scientific instrument into a polar orbit, so it eventually flies over all biomes.

Like other scientific instruments, the GRAVMAX can only hold one Gravity Scan at a time. In order to reuse the instrument, the scan must be removed; this can be done by a Kerbal on EVA, or by an Experiment Storage Unit (or probe core with built-in storage functionality).

Environmental sensor

This instrument shows the gravity in your current sphere of influence to a maximum of 4 significant figures and two decimal places. This can be used with altitude to estimate the mass of the nearest celestial body or to measure its surface gravity. Alternatively, it can be used with the accelerometer and altitude to make landing estimates.

While active, the gravimeter drains 0.0075 electric charge per second (27 E/hr).

The detector does not function in high orbits depending on the orbited body. Last known working altitudes and values at them:

Trivia

  • The name "Gravioli" may be a play on the word ravioli.
  • Despite the warning, no "positive gravioli particles" exist ingame.
