Asteria Coeli

Description

Asteria Coeli for Android is not a planetarium simulator, but designed analog to a paper atlas for the purpose of looking up sky positions of celestial objects. The electronic form takes advantage of zooming and selection of features to be displayed or not -- possibilities which are not available to paper.

The star chart is plotted on equatorial coordinates centered on a selected object of interest. A star chart can be saved to external memory card for documentation purposes, such as for printing, websites or blogs. For this purpose a monochrome display is provided.

Images of stars and deepsky objects can be downloaded from NASA's SkyView. In order not to burden the SkyView server, image size is limited to 640 x 320 pixels, while the field of view is based on a star's magnitude and a deepsky object's angular size, where 3 degrees of arc are the maximum.

Asteria Coeli adds a configurable planisphere view including stars, constellations, sun, moon, planets and four comets, plus Sun and Moon information, such as rise & set and ephemerides.

Global 3D surface views are available for solar system planets as is a fully fledged moon calendar, a moon atlas and a Sun path plot.

An abundant and partly illustrated astronomy quiz has been added for those eager to learn the easy way. To provide some help, the quiz offers two means of assistance, 50/50 narrow-down or a hint.

Asteria Coeli runs under Android 2.2.2 and higher on phones and tablets, but is strongly recommended for tablets or phones with screens larger than 4 inches across running Android 3 or higher. Both, portrait and landscape modes are supported where meaningful while the landscape orientation is most rewarding.

Waiting for Ceres

Description

"Waiting for Ceres" is software for those who can't wait for the first hi-res images from Ceres' surface expected to be received from NASA's spacecraft Dawn in 2015. Well, this app won't shorten the time until then, but provide you with current information about the craft's flight to the Asteroid Belt, news updates, information about Ceres with current ephemerides, plus an expandable Ceres Quiz.

The dwarf-planet Ceres is 13 times smaller than Earth orbiting in the main asteroid belt between Mars and Jupiter, nearer to Mars, though. NASA's spacecraft Dawn which successfully explored the largest known asteroid Vesta is currently enroute to Ceres, ETA spring 2015. Since early 2014, astronomers found reason to assume that Ceres harbors an underground ocean, perhaps about 100km thick, containing more water than on Earth. - if this model is true. The Dawn spacecraft may return finer details next year.

To date, NASA has not published exact date and time of arrival, in that the counter will require adjustment as new details from NASA check in.

Comet Monitor

Description

Comet Monitor is software for the purpose of following current position of comets. It is composed of two databases, a star chart, a data screen, a Sky View screen and a Ephemerides table.

Comet Monitor comes with two databases. "Selected JPL" is a selection of popular imaged comets using elements from JPL, while "Observable MPC" is the elements database of observable comets by the Minor Planet Center (MPC) without image icons. If you wish to have an imaged comet transferred to the "Selected JPL" database, please send the author an email with your comet icon (128 x 128) photo.

The orbital elements will be updated on regular basis and can be downloaded at any time. An update notification is not planned for privacy reasons, since this application does not send any data out of your device, but would be necessary for checking your current database version. Internet Permission is required for database updates and download of Sky View images. Once downloaded images are saved and available offline and can be updated online any time.

GPS Persmission is for those who prefer to set local coordinates via GPS. Coordinates can also be input manually without GPS.

The decimal accuracy of comet ephemerides is exaggerated in order to demonstrate how fast or slow things are changing. The computed data is in good agreement with NASA's Horizons data, however, not recommended for high precision astrometry.

The use of this software, designed for amateur astronomers, requires familiarity with astronomy and the use of your device. A Help page is bundled and accessible from the main menu.

This application operates in landscape mode only and requires presence of an external storage card. Of course best viewed with tablets.

Sky Lounge

Description

Sky Lounge is the Android interface to NASA's "Sky View" available at http://skyview.gsfc.nasa.gov/. While Sky View's web interface is rather complex and designed for the experienced astromoner, Sky Lounge's user interface concentrates on the essential parameters and is therefore more intuitive and easy to use.

The size of images downloaded with Sky Lounge is as large or as small as the device screen in pixels. In order to minimize server load, the maximum selectable field of view is limited to 7 degrees, which well embraces NGC 7000 (the North America Nebula in Cygnus).

Downloaded images are saved to the memory card in a folder named "skylounge". If an image with given parameters already exists locally, it will be loaded from memory, rather than being downloaded.

Sky Lounge is designed for tablets in landscape mode (normal and reverse) running Android 3/4. It will run on phones, however, the screen would look rather crowded and ugly.

Sphere Builder

Description

Sphere Builder is software for creating 3D planet and planetary moon globes as illustrations for astronomical documents, web sites, applications, etc.

Sphere Builder comes with textures of all planets (sorry, Saturn not yet with rings), 22 planetary moons and 16 exoplanet classes. In addition, you can create plain colored globes and add overlays.

Custom textures can be added to external memory (required). Most Android devices expect textures to be sized to the power of two, i.e., 256 x 128, 512 x 256, 1024 x 512, etc. Larger textures will result in finer globes, however at the expense of CPU load and memory. Most phones can handle texture sizes up to 4096 x 2048.

The size of saved square images depends on your phone's screen width in pixels. If your screen is 640 pixels wide, the saved image will be 640 x 640 pixels in PNG format. A small collection of samples are copied to the SD card at first run.

Sphere Builder loads an internal or external custom texture and wraps it around a globe. You can then change the brightness, longitude and latitude of the night shadow or remove it.

A globe can be rotated or panned with your finger while zooming and reset to default values are provided as well.

A configured image can be saved from within the application. If your phone runs Android 2.2 or higher then you may as well wish to take a screen snap. Press the home and the power key simutaneously to save the screen to an image file.

Over 40 spacecraft images (probes, ISS, shuttles, etc.) are included for overlay before saving.

If not for required for illustrations, Sphere Builder is an ideal viewer of 3D planets and moons. Use of this software provides basic knowledge of astronomy.

Magnetic Field Scanner

Description

This application is considered a fun application and must not be used in critical situations.

There is a number of so-called Metal Detectors out there in the market. This is often irritating since the phone's magnetic sensor reacts on magnetism rather than on metals. Some metals, however, carry a magnetic field, such as a pair of scissors or a screw driver. Gold and silver do not assume magnetism in that an application like this is not capable of detecting treasures.

However, the Android magnetic sensor, if incorporated, is well capable of detecting objects, such as loudspeakers, cell phones, refridgerators and anything that contains magnetism.

Not all Android phones and tablets employ the same magnetic hardware sensor, in that sensitivity and accuracy may vary by manufacturer. Some devices do not provide a magnetic sensor at all.

The application computes the total magnetic field, TMF, magnitude from rectangular XYZ components by squaring:
TMF = √X² + Y² + Z² [µTesla]

A few field tests resulted in positive detection of magnetized objects, such as pipes, drum cans, scoops, fences, etc. However, what is the purpose of scanning objects that can be seen and touched? A real-world test should involve detection of objects buried underground or in a wall.

Anyway, please try it yourself. If it won't work for you it will at least guide you to the location of the magnetic sensor in your phone - if it has one.

Reference Database

Description

Here is a simple but efficient product database for electronic devices. This is not an existing project, neither sold nor in use, but for demonstration purposes only.

Three basic modes for searching products are provided, query by manufacturer, by application or manual input. Upon tap on a product, the user can download PDF data sheets or send an email request if not currently posted online.

The list of manufacturers allows access to contact data and time zone information for the salesman to check overseas office hours.

The core database is of a standard format which allows in-house maintenance by the client. Distribution of database updates is facilitated by means of download from the corporate server.

Development Services for Android Phones

Since Jan 2011, Requio Web Design adds software development for Android phones to its list of services.

For instance, a database of your products for your customers and/or sales force on the road, or a website tailored to the phone's screen dimensions.

Requio specializes in applications for astronomy, sciences, electronics, plus databases and ebooks.

Software development is illfamed for proud development costs, however, this must not always be the case. Requio works without engineering charge, in that you pay only for what you get and really need. Software (and websites) are often packed with features which do not serve any useful purpose. Features and functions can be added at a later stage, so let's begin economically and grow step-by-step after careful feasability study.

Requio Applications and Privacy

Requio's applications for Android smartphones honor your privacy in every respect. None of the software transmits any data out of your phone, nor is your phone being crawled for data, such as your contacts.

Free-of-charge applications developed by Requio are also free-of-advertisements!

Most of Requio's applications use a module that is called a 'web view' for the only purpose of displaying a help file written in HTML. This web view causes a warning about internet permission, however, it only reads the internal help file, and does not send any data to the internet. Applications which download images, such as NASA photos, naturally require internet permission in spite of receiving only.

Phone permission warnings are raised when an application accesses functions in the operating system of your phone, such as menu icons or sounds.

External memory card related permission warnings are raised when an application is designed for move to SD, or when a file dialog is used. Requio applications never manipulate files in your SD that are not generated by themselves.

If, whilst using Requio applications, any wireless data traffic should occur, then this is caused by your cell provider and/or Google, but never by the application.

The Google Android Market (now 'Google Play') is the only company authorized to carry and sell Requio applications, a service for which they are cashing 35% from every paid download plus a one-time 25US$ registration fee.

If in doubt, you are welcome to contact Requio by email for pre-sale questions before you download. Comments posted in Google Play cannot be replied by developers.

If you purchased or got an illegal copy of a Requio application, this privacy statement is set out of force, simply because such copies are beyond Requio's control while Requio does not engage with crime.
